Description
Solar Collector with FMHPA, CFD Simulation Training by ANSYS Fluent
The present simulation is about a Solar Collector with FMHPA CFD Simulation via ANSYS Fluent. In this project, a collector is designed, located inside a computational zone with a parabolic cross-section. This parabolic zone is considered the surrounding air environment, responsible for radiation heat transfer from the sun.
The outer part of the collector is modeled as a cylinder. Its outer layer is glass, which acts as a solar heat absorber.
There are flat micro-heat pipe arrays (FMHPA) inside these glass layers. This system consists of several rows of pipes with a square cross-section and micro dimensions. The system’s working fluid enters these pipes. After receiving the heat caused by radiation, the temperature rises and turns into hot vapor; Hence, this part is also called the evaporation zone.
The high-temperature working fluid is then transferred to the outside of the system and exposed to the heat exchanger airflow used at the end of the collector. In this part, the fluid loses its heat and becomes condensed; Hence, this part is also called the condensation zone.
Between the layers of cylindrical glass and these micro-pipe arrays, there is a gap space in which the air inside is responsible for sucking the hot air from the solar radiation towards the micro-pipes. This modeling uses radiation and solar ray tracing models to apply for heat transfer due to solar radiation.
In the settings of this section, the geographical coordinates of the angle of solar radiation relative to the collector, along with the longitude and latitude of the location of the collector and the time and date of the solar radiation, are determined.
Geometry & Mesh
The present geometry is designed in a 3D model via Design Modeler. The computational zone is related to the space of an outdoor air environment. Inside this ambient space, a cylindrical collector is modeled. The outer layer of this collector is radiant heat-absorbing glass layers.
Then an air-gap layer is placed. Finally, FMPHA consisting of several rows of micro-sized pipes is modeled. The first part of this system is called the evaporation zone, and the last part is called the condensation zone.
The mesh of the present model has been done via ANSYS Meshing. Mesh is structured, and the number of production cells equals 153680.
Assumptions used in this simulation:
- Pressure-based solver is used.
- The present simulation is unsteady.
- The effect of gravity on the model is considered, and the gravitational acceleration is defined as 9.81 m.s-2.

Collector with FMHPA Results
After calculation, 2D and 3D contours related to temperature, pressure, and velocity are obtained. The contours show that the working fluid in the initial part of the FMHPA (evaporation zone) receives heat, and the temperature rises.
This heat is transmitted to the FMHPA through the absorbent glass layer of the solar radiation and the air-gap space. Then, the high-temperature working fluid loses heat at the end of the FMHPA (condensation zone), and the temperature decreases.

The project results described the changes in temperature across the FMHPA in the evaporation and condensation zones. Could you explain a bit about how the collector’s performance affects the overall efficiency of the system?
MR CFD Support –
The collector’s performance is crucial for system efficiency. By effectively absorbing and transferring solar radiation into heat within the FMHPA, the system maximizes the heat energy that can be utilized. This is evidenced by the temperature rise in the working fluid—the higher the temperature increase, the more energy is captured and converted. Efficient heat transfer in the evaporation zone and proper condensation in the condensation zone ensure that the system operates optimally. If the collector is performing well, the system efficiency would typically be high due to maximal utilization of available solar energy.
