Thermal energy can be used to produce electrical energy. For this purpose, unique devices called solar thermal collectors are used. The purpose of the solar thermal collector is to absorb the sun’s radiant energy and transfer significant heat to a fluid.

The flow inlet for the pipe placed under the solar panel in this analysis is defined as Velocity Inlet. Its value is considered equal to 0.01 m/s with a temperature of 290 k. The flow output in the solution domain is also determined as Outflow. The tube body is made of copper, and the solar collector plate is made of glass.

The geometry required for this analysis was generated by ANSYS Design Modeler software, and the meshing was generated by ANSYS Meshing software. The type of grid used in this analysis is structured, and the total number of cells produced for this geometry equals 1,496,700 cells.

Methodology: Flat Plate Solar Collector Conjugated Heat Transfer

In this analysis, K-epsilon Realizable Turbulence Viscosity Model and Pressure-Based solver are used to check the fluid flow. According to the nature of the fluid inside the fuel chamber, it is necessary to solve the energy equation together with the momentum equations. In this CFD simulation, the Radiation model is used in Discrete Ordinate mode and Solar Loading mode to investigate the heat transfer from the sun.


Since the main purpose of the issue is to investigate the heat transfer inside the Solar Collector and the flow velocity, its contours and vectors can be seen in the figures. Two-dimensional and three-dimensional contours related to temperature and velocity were obtained. This simulation is carried out in a steady state, which tells us that fluid motion is independent of time.

In the case of heat transfer, it is visible in the figures that the fluid temperature increases significantly by getting the heat via the convection phenomenon.

For a closer look, water enters the domain with a temperature of 290K. It exits from the outlet boundary condition with a maximum temperature of 295.85K, which is more than a 2% increase in total temperature. Also, the total heat transfer rate that affects the water flowing in the pipe is equal to 9.8639W.

It should be noted that in this simulation, all the heat transfer methods, which are Conduction, Convection, and Radiation, are used.
