Week 5 - Curve fitting

Aim: To set up steady-state simulations to compare the mixing effectiveness when hot inlet temperature is 360C & the Cold inlet is at 190C.           To use the k-epsilon and k-omega SST model for the first case and based on judgment use the more suitable model for further cases.…

Aim:  To write a script that does the following. The script should take column numbers as the input and plot the respective columns as separate images Each file should be saved by the name of the column The plot labels should be extracted from the file. If, I request for a plot between column 1 (crank angle) and column…

Aim: To write code to fit a linear and cubic polynomial for the Cp data. Explain the results are good or bad.  What is 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…

Aim: To write a program that solves the following ODE, which governs the motion of a Simple Harmonic Motion(SHM) and make a pendulum equation using python. Theory: What is Differential equation? Ans: A differential equation is the one which involved with the one or more deriavtives including the study of change. What is…

Aim:  To write a code on Otto cycle and calculate its thermodynamic efficiency To plot a P-V diagram both actual and theoritical considering engine kinematics formula. Theory: Otto cycle is named after Nikolas August Otto. This Otto cycle is also known as constant volume cycle. These cycle generally used in gasoline…

Aim: • To check for the geometrical errors and deleting surfaces which are unwanted for Surface wrap, and • After clearing geometry, To merge all 3 models and perform surface wrap. What is Surface Wrappng? Ans: The surface wrapper wraps the geometry of interest to create a volume that does NOT have…
