Fluid 1
 
Data of the fluid

This fluid is the only real fluid studied here. And it is one of the most common because it is Water.
Some useful properties can be reminded:
Rho=1 000 kg/m-3
Nu=1e-6 m2/s
Cp=4 182 J/kg/K
Pr=7


Velocity field

Three rolls appear for water in the case where the gradient of temperature is 0.5 degrees for 1 cm between both plates.

Whereas the numerical results are Vx max=1.52e-4 ms and Vy max= 2.29e-4 ms, theoretical calculations give Vx th=2.25e-4 ms and Vy th= 2.29e-4 ms
