Project 1 - Simulating a BTMS

1. Create an excel calculator to estimate the volumetric energy source as close as possible for the dimension of the cell in the made-up BTMS. Show your work and cite your references.

2. While performing a steady-state simulation, is it OK to use any solid material? Use the analytical equation that was derived in the previous lectures to prove that the material properties are relevant or irrelevant while performing a steady-state simulation

Yes, it is okay to use any material as in the steady state CFD simulation.

3. For a baseline element length of 12,8,6 and 4mm, what is the number of iterations required for convergence? Plot this trend and explain the result. Assume volumetric heat source to be equal to 30000 W/m^3 and set inlet velocity to 4m/s

Baseline element length = 12 mm

Volume Avg of Temp. = 302.54132 K

Baseline element length = 8 mm

Volume Avg of Temp. = 302.48712 K

Baseline element length = 6 mm

Volume Avg of Temp. = 302.53178 K

Baseline element length = 4 mm

Volume Avg of Temp. = 302.56224 K

Baseline element length	Iteration for Convergence
12	1200
8	1200
6	1500
4	1500

After solving the given BTMS problem with 4 different baseline element lengths it can be observed that 12 mm is enough for this analysis as the volume avg of temp. remains same for the all the mesh sizes, and it also takes less no. of iterations for convergence.
