Abstract:

Similarity solution ofheat and mass transfer in a thin liquid film over amoving saturated porous medium in the presence of thermal radiation has been considered. By using shooting technique, the governing coupled nonlinear partial differential equations are transformed into coupled nonlinear ordinary differential equations in MATLAB.The flow phenomenon has been characterized with the help of obtained flow controlling parameters such asPrandtl number, Darcy number, Schmidt numberand other driving parameters. The effects of dimensionless parameters on the boundary layer velocity, temperature and concentration profiles are presented both analytically and graphically.Moreover, the physical parameters such as skin friction, local Nusselt number as well as local Sherwood number are presented both analytically and graphically.

Abstract:

Biogas is obtained from biomethanation of biomass waste. The present work aims at a detailed discussion of the different factors affecting the perforation of biomethanation process. Some case studies have been presented to show the techno-economical feasibility of different plants, based on different locally available biomass. In most of the cases plants are installed against adequate financial support with subsidy, but the performance of the plants is being affected due to lack of technical knowhow. Effects of different process parameters such as PH-value, temperature, C/N ratio on biogas generation, needs to be taken care of to ensure maximum generation rate with highest yield. Since biomass is locally available, harnessing energy from it may be a probable solution to end the energy crisis in rural areas which are remote from the power grid, thereby providing immense potential for electrification, application to a large number of industries and last but not the least domestic purpose using Biogas.

https://doi.org/10.26782/jmcms.2018.08.00004

Abstract:

This paper develops a digital model of a current source Inverter fed three phase synchronous motor drive system from the view point of steady state stability aspect. The motivation lies in the fact that to control any electrical drive system digital controller is needed. To develop the software and hardware of such controller, a suitable digital model of the original drive system becomes necessary. Approach to develop the model in s-domain has been outlined and then z-transform has been applied. Different aspects of the model like the stability assessment using pole-zero mapping, Jury’s test, range of coefficients of characteristic equation for stability etc., have been computed leading to various graphical plots. Furthermore perturbation of machine design parameters have been modeled from the view point of stability assessment with necessary computational results.

Abstract:

Signal attenuation due to rain is an important barrier in the Microwave Communication field. In the terrestrial region like South-East Asia the microwave signals operating at higher frequency ranges are attenuated due to rain and other atmospheric obstacles like water vapor, ice particle etc. In this paper we have used different MIMO techniques like 2×2, 3×3 and 4×4 and also constructed a model. We study the frequency diversity improvement factor for the developed model for different fade margins using 4X4 MIMO techniques. Then we compare this study with ITU-R model. We have got the better result for prediction model using 4×4 MIMO techniques for the frequency range 50-90 GHz.

https://doi.org/10.26782/jmcms.2018.08.00006

Abstract:

In this paper, authors have considered the issue of slow convergence and moderate Bit Error Rate (BER) of Constant Modulus Algorithm used for channel equalization. Constant Modulus Algorithm (CMA), an extensively used gradient descent based unsupervised algorithm for QAM Signal, suffers from the poor convergence property as well as poor BER. Two novel blind equalization algorithms have been proposed which overcomes the problem of slow convergence and poor BER associated with CMA. Proposed algorithm incorporates modified CMA-like error function based on mean forth error criteria into Rprop frame work. Matlab Simulation of the proposed Rprop Based Improved Constant Modulus Type (RICMT) algorithm offers better result in terms of convergence, inter symbol interference (ISI) and bit error rate (BER) in a linear channel as well as for nonlinear channel in comparison to the CMA Equalizer for noisy environment.

Abstract:

Now a days, the rapid need for electrical energy all over the world has put electrical power system under great stress. Due to day by day decrease in available conventional energy sources, researchers are shifting towards non-conventional energy resources or Dispersed generation (DG). DG is becoming a feasible alternative to overcome the power deficiency due to reduction in power losses, system reliability, and availability of power at consumer’s premises. With this need of DG, it’s important to analyze the adverse impact of DG on distributed power system. This research analyzes the effects of induction generator and synchronous generators on distribution system. The main outcome and objective of this research is to find optimum type, size and placement of DG to be injected in distributed system in order to have minimum impact on power losses of the system. By using globally renowned and modern software Electrical Transient Analyzer Program (ETAP) and taking Rahman Baba electricity distribution network as a test case. After analyzing, the results show that injecting DG has positive impacts on power losses at certain buses while 30% of power losses were decreased when induction generator as a DG unit was integrated with the distribution network in the optimum location. Also positive impacts of DG unit on power losses has been seen by injecting undeterministic small amount of synchronous generator as a DG unit and by increasing cross-sectional area of the conductor has showed much improvement in power losses.

Abstract:

The speed control is an interesting and important term in control system engineering. Speed of the DC servomotor has to be varied according to application requirement. According to requirement suitable controllers and algorithm are use to achieve best control over speed. PID controller is a well known controller which is used in feedback control in industrial application. But in some industrial application the speed control with PID controller is not able to achieve the perfect control due to non linear element present in the system. Therefore in this research the Particle Swarm Optimization based PID controller and Hybrid Fuzzy Logic Controller are use to overcome this problem. Fuzzy logic control offers an improvement in the quality of the speed response concentrated by emulating the expert and implemented in language based on operator’s experience. Particle Swarm Optimization algorithm on the PID controller is an advanced approach for getting a stable and linear response of any system. PSO is a population based stochastic optimization technique is initialized with a population of random solutions and searches for optima by updating generations. A comparative analysis of performance analysis both the controllers have been done.

Design approach to a wound rotor induction motor towards optimization

Abstract:

About 88% of the driving power is produced by 3-phase and single-phase induction motors. In most part it is by squirrel-cage motors, only a small fraction by the slip-ring or phase-wound type. It is because the cage-type motors are relatively inexpensive. But they suffer from low p.f. operation and low starting torque which cannot be manipulated by inserting resistance in the rotor circuit. Also, this type of induction motors is not easily speed-adjustable. Though a little more expensive, the slip-ring type induction motors do not have these disadvantages. Therefore, they are used as speed-adjustable drives and for drives where heavy duty starting is involved. The design of any kind of power equipment should be made cost-optimally in the present day competitive market. A new approach to reaching optimal solution has been shown in this paper by the method of sequential searching with respect to the chosen design variables. Also, another design has been made following a hybrid of analytical and synthetic approach. The design variables have been chosen from designers’ experience. In contrary to the popular belief that there is no need for going in for complexity of optimal design, the quasi-optimal solution may be obtained by the designer from his accumulated experience, we find that the idea is wrong. The optimal design approach saves a lot of money.
