DESCRIPTION:         In this report, we will be studying the effects of the grid points in the first order convection equation describing one dimensional velocity distribution.   `frac{delu}{delt} = c*frac{delu}{delx}`   CODE: clear all close all clc %inputs c = 1; %convective coefficient…

DESCRIPTION: In this code, we are going to compare the results of the 1D convection distribution equation describing the velocity for a range of time-step values. As a result, we will be getting the plots on the final velocity profile on time marching and computational time for each value of timestep. MAIN CODE: clear…

DESCRIPTION:      In this code, we are going to discretize the function for the first-order derivative using first, second and fourth order approximation techniques and studying the error bounced by every method by a bar chart.   CODE: clear all close all clc x = pi/3; dx = pi/100; %y = (sinx)/(x^3)…

STOICHIOMETRIC COMBUSTION   DESCRIPTION:   Stoichiometric combustion defines the ideal combustion that needs to take place for a given chemical equation. This is actually the general form of equation for alkanes. The general form might differ for each of the Carbon family: Alkanes, Alkenes and Alkynes as…

DESCRIPTION:      Here in this code, we are using a range of dx terms for discretizing the first order derivative and studying the results of the dx vs error plot  CODE: clear all close all clc x = pi/3; dx = linspace(pi/4,pi/4000,30); %y = (sinx)/(x^3) %actual dy by equation dy = (x^3 *cos(x) - 3*x^2…

DESCRIPTION: Using the central and skewed scheme methods initially, we have to develop the Taylor table, which should be converted into a matrix and solved for the constants. These constants help in solving the second order differential equation. Finally, the error results are plotted and studied.   1. CENTRAL DIFFERENCING…

DESCRIPTION:                        ode45 is an inbuilt function in Matlab, which is used to solve the ordinary differential equations by its inbuilt integration process. Here in this program, we are going to solve the second order ode which describes the motion…

Introduction:     Heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant, where it is dissipated away from the device, thereby allowing regulation of the device's temperature. In computers, heat sinks…

Objective of the project: In this project, we are going to analyse an electronic enclosure using ANSYS Icepak platform. An Electrical enclosure is a cabinet for electrical or electronic equipment to mount switches, knobs and displays and to prevent electrical…

1. Problem description:    In this project, We are going to model and analyse a Cold plate cooling model using ANSYS Icepak. The model includes two heated plates, cooled by water circulating inside the cold-plate cavity, as well as by air driven by natural convection externally. Separately meshed assemblies…

Introduction:    Low voltage panel is a component of an electrical distribution system that divides an electrical power feed into branch circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure. In essence, panelboards are used to protect against electrical overloads…

1. Introduction An Icepak 3D fan object may sometimes behave differently from real fan behavior. Typically this is due to flow features like swirl and centrifugal spread resultant from the spinning fan rotor as well as the rotor blade geometry. In an Icepak fan based setup, this swirl is estimated and calculated off a…

1. Problem description: In this project, we will be analysing the hanging node assembly provided. Without any modifications, the model results in about 750,000 elements. Note that this mesh count results from using the non-conformal meshing technique, which reduces mesh bleeding and mesh count. However, this mesh does…

Introduction: A printed circuit board (PCB) is generally a multi-layered board made of dielectric material and several layers of traces. From the thermal modeling point of view, a PCB may be treated as a homogeneous material with bi-directional thermal conductivity, i.e. thermal conductivity value is different in the normal-to-plane…
