What is a Fuel cell:                                                       A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen)and an oxidizing…

Electric vehicles (EV), Single battery cells are serially and parallelly connected to make a battery stack to achieve higher voltage and capacity. However, the charging and discharging process need to stop as soon as any cell reaches its maximum limit or working threshold (below the absolute threshold). Due to this,the…

1. Thermal Management Techniques for EV Electric vehicles (EVs) develop fast and have become popular due to their zero-emission and high tank-to-wheels efficiency. However, some factors limit the development of the electric vehicle, especially the performance, cost, lifetime and safety of the battery. Therefore, the management…

Aim: Compare 3S4P AND 4P3S battery pack configurations and comment on the results. Procedure: Firstly we need to decide upon which battery block to use out of all available battery blocks in MATLAB.

What is Battery ? Batteries are a collection of one or more cells whose chemical reactions create a flow of electrons in a circuit. All batteries are made up of three basic components: an anode (the '-' side), a cathode (the '+' side), and some kind of electrolyte (a substance that chemically reacts with the anode and…

Aim: Frontal Crash Simulation Procedure: In this project, we need a car model and it should be a solver deck file ( 0000.rad and 0001.rad). So in our case, we have used BIW of a car only. A complete file will be too big to handle and take more processing time. So to start analyzing the result for the frontal crash…

Aim: Side Pole Crash Simulation Procedure: In this project, we need a car model and it should be a solver deck file ( 0000.rad and 0001.rad). So in our case, we have used BIW of a car only. A complete file will be too big to handle and take more processing time. So to start analyzing the result for the side crash we need…

Aim: Meshing the provided component and later analyzing results by making several changes in solver configurations. Procedure:  Now, as we know first we need to do mesh on the provided model to make it ready for analysis. And to start with mesh one should always check for geometric errors first in the model. So our…

Aim: Study the behaviour of provided model using different material laws and failure models along with material laws and concluding which case be best for on-field scenario. Procedure: Now, we already know from earlier project i.e. Assignment 3 what we need to access model in radioss and how to proceed with starter…

Aim: Study the behaviour of provided model with and without changing the material properties of it and also see how can we control animation using engine 0001.rad file for the same model. Procedure: Now, to study all these behaviour of model in radioss we need a starter file i.e. 0000.rad and engine file i.e. 0001.rad…

Aim: Meshing and providing connections to Suspension Assembly. Procedure: Firstly, we need to arrange a CAD model with good quality for doing all these tasks. It is provided to us already and it should be in provided formats only (i.e. step, iges, stl) so that it is workable in ANSA workbench.  Now before starting…

Aim: Meshing the provided model of Instrument Panel Substrate. Procedure: Before doing any operation on provided model it is always better to know little about it. So, instrument panels are often made of acrylonitrile-butadiene-styrene (ABS), ABS/polycarbonate alloys, polycarbonates, polypropylene, modified polyphenylene…

The Rankine cycle is a model used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.…

File Parsing : Different Organisations comes up with polynomials that can be used to evaluate different properties for different environments for ex. in case of thermodynamics such as Cp, H and S. They also create a document file for the co-efficients that are required to evaluate these polynomials, for n no. of species.…

Stalagmite Function: Stalagmites represents the 3D pointed formations that arises from the floor. Like cones but may or may not be pointed always. With refrence to data here, Stalagmites are the 3D curves formations because of data we gave and it helps finding the threshold value of a parametres.    It creates…

Curve fitting: Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed…

What is 2nd Order ODE's?    A Differential Equation is an equation with a function and one or more of its derivatives. Order The Order is the highest derivative.                     Now, this works in Engineering: In Engineering, ODE is used to describe the transient…
