In this project, simulation of flow over NACA 0017 airfoil is performed using Flow Simulations add in of Solidworks. To generate the co-ordinates of NACA 0017, the following data was fed into NACA 4 digit generator of airfoiltools.com These co-ordinates were copied into a text file, a column with all rows zero was added…

In this project, transient 3D simulation of flow of air over a cylinder of diameter 0.02m and length 0.2m is performed using Flow Simulations add in of Solidworks. The cross-section of the cylinder is in the XY plane, while its length is in the z direction. The free stream velocity is in the X direction.Initial studies…

Introduction In this project, the effect of Reynolds Number on the flow through a pipe is studied through numerical simulations using Flow Simulations add-in of Solidworks. Simulations are carried out for flow of water through a pipe of internal radius 2.5cm and length 20cm. The boundary conditions are as follows:1. Inlet…

Using the Taylor Table method, the fourth order approximate finite difference scheme for the second order derivative has been derived for 3 different stencils. 1. CENTRAL DIFFERENCE SCHEME To derive the fourth order approximate central difference scheme for the second order derivative, we use the following formula: `n…

1. What does popt and pcov mean? popt stores the values of the co-efficients of the polynomial passed to the function curve_fit. The      function curve_fit calculates these co-efficients and popt stores them. pcov : It is a 2D array which gives the estimated co-variance of popt. The diagonals provide…
