1. Opening the \'therm.dat\' file in reading mode. 2. Ignoring the title line, and storing the global max, mid and min in parameters. 3. Defining temperture range in between global max and min values. 4. Ignoring the comments (that starts with \'!\'). 5. Taking the species namein \'inp\' variable. 6. Searching the species…

Flow Simulation over a NACA airfoil is carried out at a velocity of 600m/s in x-direction, for different angle of attack, viz. 0,2,4,6,8 and 10. In the following model, only 0 degree angle of attack is shown(but for results it was changed over and over again).  https://drive.google.com/file/d/11rI_5kAaZtmLemt56M0zAcReNxOLuJ8w/view?usp=sharing…

1. What does popt and pcov mean? A. On using curve_fit command, it returns the optimum coefficients in the function defination which is stored in popt; and pcov stores the estimated covariance of popt in a matrix form (the diagonals provides the variance). 2. What does np.array(temperature) do? A. This command will call…

Genetic Algorithm is an optimisation technique which works on natural selection of randomly generated values. It first selects a particular set of values from the total values, then performs some function to it, to produce optimised value, and then repeat the same procedure to some extend.  In MATLAB, ga is inbuilt…

Air is flown through a pipe of diameter 5mm and length 25mm. The simulation is studied assuming density of air 1.225 kg/m^3 and dynamic viscosity 0.00181 Pa-s.  Three probes at 85%,90% and 95% of the pipe length are drawn. https://drive.google.com/file/d/1oNWRh2pgLm76yixQFUVjcc8wCW3lFsM9/view?usp=sharing For Renold's…
