Solving Steady state and Unsteady state 2-D Conduction Equation

STEADY VS UNSTEADY FLOW OVER A CYLINDER  The aim is to simulate the flow over a cylinder for both steady-state and transient cases and observe the Von Karman Vortex Street. Von Karman Vortex street is a repeating pattern of swirling vortices caused by a process known as vortex shedding which is responsible for the unsteady…

MIXING EFFICIENCY    Performing steady-state simulations to compare the mixing effectiveness when the hot inlet temperature is 36C(309.15K) and 19C(292.15) are entrained from the X-Axis and Y-Axis respectively. We will also determine what is the effect of changing the momentum ratio. Also, different turbulence models(K-Epsilon…

SCOPE  In this paper, we are going to study about the various techniques used for processing and conditioning DC electrical energy to AC. A qualitative approach is used to describe various concepts with the help of Simulink. COMPONENTS & SYSTEMS The fundamental components and systems that are required to carry…

1) BRAKING ENERGY A significant amount of energy is consumed in braking. To stop a car entirely, the kinetic energy of the moving vehicle has to be absorbed.   Braking power and braking energy consumed by the front and rear wheels are closely related to the braking forces on the front and rear wheels. Ignoring the…

ELECTRIC VEHICLE MODELLING IN MATLAB-SIMULINK   I) VEHICLE SUBSYSTEM The vehicle subsystem consists of  * Vehicle Body * Tire model * Wind and Terrain  * Brakes    A half-car model is used since we are modelling the longitudinal dynamics of the vehicle a half car model will suffice since the loads…

  Simulate 2-D Steady-state and unsteady state conduction equation   2-D Conduction equation `(partialT)/(partialt) = alpha.[(partial^2T)/(partialx^2) + (partial^2T)/(partialy^2)]`   STEADY STATE EQUATION `[(partial^2T)/(partialx^2) + (partial^2T)/(partialy^2)] = 0`   Discretization `T(i,j) = (T(i+1,j)…

      1) SPEED CONTROL OF DC MOTOR USING H-Bridge. The H-bridge consists of four IGBT/Diode pairs. Two transistors are switched simultaneously: Q1 and Q4 or Q2 and Q3. When Q1 and Q4 are fired, a positive voltage is applied to the motor and diodes D2-D3 operate as free-wheeling diodes when Q1 and Q4 are…

1) MAPPED VS DYNAMIC   2) CALCULATION OF MPG       3) WIDE OPEN THROTTLE OF HEV We will simulate the Wide-open throttle response for the HEV model, and compare the changes in various parameters when the simulation is done with Air drag and Gradeability.   Results ( 0 gradeability and 0 Air drag)…

The Matlab script takes the NO LOAD & BLOCKED ROTOR TEST data and calculates the relevant parameters and plots the torque-speed curve of the induction motor.   %% Equivalent circuit analysis of an induction motor % Computation of Induction parameters and Torque vs speed performance from locked rotor and no load…

DC MOTOR CHARACTERISTICS       Now, keeping these parameters in mind I have scripted a MATLAB code. Plotting the Angular velocity and the Motor torque, the user can input the Motor parameters ( Operating voltage, Motor constant and Armature resistance)     clear all close all clc % Motor torque…
