AIM – To run a pipe flow simulation with an inlet Reynolds number of 100, 1000 and 10000. For each of these cases do the following Place the line probes at 95%, 90%, 85%of the pipe length. Compare the normalized velocity profile at each of these locations. Normalize the velocity profile by the inlet velocity. Reynolds…

OBJECTIVE – We have to write the script which should take column numbers as the input and plot the respective columns as separate images. The plot labels should be extracted from the file. If there is a request for a plot between column 1(crank angle) and column 8(volume) , then label information should automatically…

  OBJECTIVE – To write a program to perform curve fitting.   Curve Fitting is the process of constructing a curve or mathematical functions, which possess the closest proximity to the real series of data. By curve fitting, we can mathematically construct the functional relationship between the observed…

The Newton Raphson method is an iterative technique that is used to find out the roots of a real valued function. It uses the idea that a continuous and differentiable function can be approximated by a straight-line tangent to it. In this case Newton Raphson method is used to find out the cushion pressure required to cut…

OBJECTIVE – To write a program to simulate the transient behaviour of a simple pendulum and to create an animation of its motion.   PROCEDURE – In Engineering, ODE is used to describe the transient behavior of a system. A simple example is a pendulum The way the pendulum moves depends on the Newtons second…

OBJECTIVE - To write a code for P_V diagram of an Otto cycle and calculate thermal efficiency   PROCEDURE – ASSUMPTIONS Initially state variables p1,t1,t3 and gamma are assumed. Necessary Engine geometric parameters are also assumed.   PROGRAM AND EXPLANATION- First the required inputs are given and with…

OBJECTIVE - 1. Write a function that extracts the 14 co-efficient and calculates the enthalpy, entropy and specific heats for all the species in the data file. Calculate the molecular weight of each species and display it in the command window. Plot the Cp, Enthalpy and Entropy for the local temperature range (low…

OBJECTIVE - Write a code in MATLAB to optimise the stalagmite function and find the global maxima of the function. PROCEDURE- The genetic algorithm is a method for solving both constrained and unconstrained optimization problems that is based on natural selection, the process that drives biological evolution.…

OBJECTIVE – To write code to fit a linear and cubic polynomial for the Cp data and plot the linear and cubic fit curves along with the raw data points.   PROCEDURE – Curve Fitting is the process of constructing a curve or mathematical functions, which possess the closest proximity to the real series of…
