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…

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…

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…

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…
