Curve Fitting

Objectives: To simulate the Prandtl Meyer expansion fan using converge and analyse the results To understand the physics behind shock waves through literature review and study the boundary conditions required to simulate such a flow To study the effect of SGS parameter on the location of shock wave and its effect on cell…

Objectives: To write a program to analyse various data plots for a converge engine output data file and calculate specefic performance parameters for the same Code Methodology: Import the required packages Initially the program tries to locate and open the data file. If file is not present or saved by a different name,…

Objectives: To write a program to curve fit for data series of Cp vs Temperature and to evaluate the goodness of fit for a linear and cubic polynomial Code Methodology: Import required packages A function is first defined to read the actual values of data for Cp and temperature to which the curve is needed to be fit. This…

Objectives: To write a program to evaluate the minimum pressure needed to break a given thickness of ice using an air cushion vehicle To determine an optimum relaxation factor for the same   Background: In determining the minimum cushion pressure needed to break a given thickness of ice using an air cushion vehicle,…

Objectives: Simulate the transient behaviour of a simple pendulum and generate an animation for the same Initial Conditions: Length of the pendulum = 1 m Mass of the ball = 1 Kg Damping coefficient = 0.05 Gravity in m/s^2 = 9.81 Simulation time = 0 - 20 seconds Initial position of mass = 0 Degrees Initial Velocity of mass…

Objectives: To solve an otto cycle for given parameters and create a PV diagram for it To calculate and output the thermal efficiency of the cycle for the given parameters Initial Conditions: Inlet pressure at start of stroke (P1) = 101325 Pa Initial Cylinder temperature (T1) = 500 K Ratio of specefic heats (gamma) = 1.4…
