What is the best solver to solve coupled partial differential equations with Initial values?
We can solve the coupled PDE's using ode45 solver. We have to define the variables first using a matrix, then we can define our equations and finally we can use ode45 solver with customized conditions.
What is the relation between Cos(2theta) and Cos(Theta)?
We can expand it using the following identity- Cos(2theta)=( Cos(Theta))^2-(Sin(Theta))^2
What is the difference between Euler-Euler and Euler-Lagrange method for solving fluid flows?
Euler-Lagrange method is used when two fluids are present and one is in dilute proportion(like 5%). We consider one fluid phase to be like particles in the other fluid. We use Euler-Euler when both fluids have comparable concentrations.
