Computational Fluid Dynamics - Analysis of a Hot Water Tank in ANSYS Fluent.
The project analyses a hot water tank built in various configurations. The tank consists of an inlet on one side and an outlet on the opposite side. The bottom of the tank is kept at a higher temperature. Water flows through the tank at different velocities and gets heated.
The exit temperature of water is analyzed for different configurations of the tank. The cross section of the tank is varied along with the inlet velocity of water. The cases are analyzed for the highest exit temperature.
The analysis was done in ANSYS Fluent with the Boussinesq density parameters and second order discretization for the solver.
The base plate temperature was kept constant in some configurations and then a non uniform parabolic variation was achieved with a User Defined Function (UDF) coded in C.
The Problem Statement and Geometry Configuration:
- The overall geometry was based on parameters, and each configuration of the geometry was simulated on ANSYS
- Indirect boundary conditions were provided as challenge projects over this default boundary condition. These were required to be fed as UDFs into ANSYS Fluent.
Simulations -
Below Images show the results, mainly the velocity streamlines of the various geometry configurations and boundary conditions.
One of the images is of the Temperature Contour of the Bottom Plate of the Geometry which was added with a User Defined Boundary Condition.
