Study of the Effect of the Porous Plates on the Tank Bottom on the Boiling Process

Abstract

In the present study, the boiling process is simulated in a fixed-temperature tank using the ANSYS FLUENT commercial software. Eulerian method is used to simulate the condensation and evaporation processes. The effect of porous media on the boiling process is investigated. For this purpose, a porous medium with different porosity coefficients is placed on the bottom of the tank and its effect on the bubble dynamics and wall thermal flux is investigated. The simulation is carried out in two dimensions and is considered as unstable. The results show that the porosity coefficient of the porous medium affects the bubble dynamics. The process of phase change decreases by decreasing porosity. Also, the growth rate of the bubble phase in the tank increases with increasing the heat transfer coefficient of the porous medium.

Improvement of Thermal Energy Storage by Integrating PCM Into Solar System

“…The heater depends mainly on two basic particles that we find in most devices of this type. It has been updated in this study by incorporating the PCM in the complex to improve and raise productivity and integrating the PCM in the tank to increase the storage capacity and the lack of storage space [5,14,15]. The proposed solar system ( Figure 1) has:…”

“…For this reason, the solar heater needs an upgrade at the stage of producing and storing thermal energy. Therefore, there are several ways to manage the thermal energy among these methods, the production and storage of thermal energy by using phase change materials (PCMs) [4,5]. They are materials that can store solar energy as latent heat and become liquid by increasing the temperature.…”
