Conical Solar Collector CFD Simulation, ANSYS Fluent Training

Solar energy is the largest source of energy in the world. This energy is clean, cheap, and endless and can be found all over the world. Solar water heaters work by absorbing solar energy from collector plates, and their heating efficiency varies by type of collector. To provide hot water during the day and the night, hot water is kept in a double-sided reservoir with thermal insulation that can keep the water temperature for up to three days without any changes in its temperature.

Conical Solar Collector Project description

In this project, heat transfer in a Conical Solar Collector CFD Simulation containing water fluid is carried out and analyzed by ANSYS Fluent software. The cubic fluid domain consists of an inlet (velocity inlet type, 1m/s) and a pressure outlet. The conical collector consists of an inlet (mass-flow type, 0.0116 Kg/s) and a pressure outlet. It also has 1 layer of glass and 1 layer of steel to decrease convection heat transfer as much as possible. The conical solar collector absorbs the sunlight and warms the water inside its tank. The energy and radiation model (solar ray tracing model) are activated and the Standard model with the use of standard wall function is exploited for fluid flow analysis. Simulations are done for two configurations: water inlet-outlet existence and non-existence (where no water is injected inside the tank and sunlight only warms the water inside the tank).

Conical Solar Collector Geometry and Mesh

The geometry for analyzing this simulation consists of a fluid domain and a conical solar collector. The geometry is designed in ANSYS design modeler® and is meshed in ANSYS meshing®. The mesh type used for this geometry is unstructured and the element number is 577397.
