coding basics
1. A=[ 1,2,3,4,5]-This means numbers-1,2,3,4,5 are saved in an array-\'A\' variable. Array:1-row X 5-columns. 2.B=[1;2;3;4;5]- This means numbers will be saved in an array-\'B\'. Array: 5-rows X 1-column. 3. C=A*B\'. This wont work because B\' is B transpose which will change B into 1X5 matrix. And we cannot multiply two…

Boundary and initial condition
Boundary conditions and initial conditions dictate particular solutions to be obtained from Partial differential equations. Though the equations of fluid flow is same -Navier stokes equation but these boundary conditions actually drive the equations to actual solution. For example no slip condition at boundary, will…

Prandtl Meyer Shock problem
Shockwave : It is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium, when a wave moves faster than the local speed of sound in a fluid. Based on characterization it can be of many types. For example based on angle: Normal shock, Oblique shocks, Bow shocks. …

Calculations were carried out using conservation and non-conservation form of Navier-Stokes Equation. -Non-conservation form: Number of cycles: most of the variations in values occurs in the initial number of time steps. But at most till 400-500 iterations, values dont change that much. And after about 1000 iterations,…
