Week 6 - Data analysis

Aim: To simulate the flow through a converging-diverging nozzle with the given boundary conditions. Theory: A nozzle is a tube of varying cross-sectional area (usually axisymmetric) aiming at increasing the speed of an outflow and controlling its direction and shape. A Converging-diverging nozzle also known as C-D nozzle…

Aim: To write a python script to analyse the data available in the given file . Objectives: Check the compatibility of the file Calculate the area under the P-V diagram.  Calculate the power output of this engine assuming that RPM is 1500 Calculate its specific fuel consumption. Theory: Data analysis can be …

Aim: To write a code in Python to fit a linear and nth order polynomial  for Cp data. Objectives: Write a python code  to fit a linear and cubic polynomial for the Cp data. Explain if your results are good or bad. Show empirically  how well your curve has been fit. Theory: Curve fitting can be defined as the process of…

Aim: To write a  program in Python that will simulate the motion of a pendulum. Objectives: Write a program that solves the ODE representing the equation of motion of a simple pendulum with damping effect. Simulate the motion between 0 to 20 seconds for an angular displacement=0, angular velocity=3 rad/s at time t=0. Governing…

Aim: To write a code to simulate  an Otto cycle and plot its Pv diagram Governing equation: Thermal efficiency of an engine can be simply given by the fraction of energy added by heat that is converted into net work output.         For an engine working on Otto cycle (like petrol engine),the thermal…

Aim: To write a MATLAB code to parse NASA thermodynamic data file and the calculate thermodynamic properties of various gas species. Objectives: Write a function that extracts the 14 coefficients and calculates the the enthalpy, entropy and specific heats for all the species in the data file.  Calculate the molecular…

Aim: To write a code in MATLAB to optimize the stalagmite function and find the global maxima of the function. Objectives: Clearly explain the concept of genetic algorithm and its syntax in MATLAB.  Plot graphs for all 3 studies and for F maximum vs number of iterations. Theory: Concept of Genetic algorithm: Genetic…
