Validation Cases Using Ansys Fluent

Posted September 18, 2018 at 07:47 by varun.vysyaraju

Objective:

Steady state heat conduction with fixed temperature at both ends.

Problem Definition:

Two ends of wall subjected to constant temperature T1 = 393 K and T2 = 323K.
Wall of length, l = 0.2 m and thickness = 0.001 m
Thermal conductivity, k = 1.2 W/m-K

Methodology:

1. Ansys Fluent was used for simulation
2. Initial condition of temperature 323 K was given to domain
3. Left wall temp = 393 K ; Right wall temp = 323 K
4. Top and bottom boundaries were taken to be adiabatic i.e. heat flux q = 0
5. Compared with analytical solution

Analytical Solution:

T(x) = ((T2-T1)/L)*x + T1

Conclusion:

Numerical simulation carried out by fluent shows good agreement with analytical result.
