“…To design a heat pipeand attain the required thermal capacity, the characteristic of the working fluid, the wick and the container must be determined. In order for the heat pipe to work properly, the pressure drop in the fluid flow has to be compensated by the pumping pressure in the wick and the capillarity as prescribed by Tardy and Sami [20,25], Endalew [9] and Reay and Kew [23];…”

“…The thermophysical properties of the working fluid used and the wick properties determine the design of the heat pipe.The physical phenomena that limit heat pipe heat transfer capillary, sonic, entrainment, boiling, frozen start up, continuum vapor, vapor pressure and condenser effects determine the lowest limit of these phenomena and are considered as a design limit. The main design limitations were extensively discussed in Tardy and Sami (2009), Faragaliet al (2008); and Reay and Kew (2006) and Tardy and Sami (2008). Interested readers in the capillary, sonic, entrainment limit and boiling limits of the heat pipes are advised to consult the aforementioned references.…”

A numerical model to predict the behavior of a novel concept of a hybrid system composed of photovoltaic-thermal solar panel and heat pipe is presented hereby. This model has been developed to assess the performance, and energy conversion process of the hybrid system as well as the individual efficiencies of this process to produce hot water and electricity. The two-dimensional heat transfer and fluid flow dynamic model was developed to describe the behavior of a hybrid system under different conditions, namely; solar irradiance, heat pipe conditions and different refrigerants. The model is based upon the dynamic mass and energy equations coupled with the heat transfer formulas, and thermodynamic properties of refrigerants as well as thermal material properties of the PV solar panel and heat pipes. Finally, the model's prediction has been validated and fairly compared with available experimental data.

“…Excellent thermal properties such as high thermal storage capacity, good heat transfer rate between the heat storage material and heat transfer fluid and good stability to avoid chemical and mechanical degradation, are the key factors to viable solar thermal energy storage system [1][2][3][4][5][6][7][8]. Phase change materials (PCMs) can store/release a significant amount of heat during melting/solidification phase change processes.…”

A mathematical model based upon the conservation and heat transfer equations has been developed to predict the thermal behavior of integrated phase change material in solar collector during thermal storage. The model includes fusion of the phase change material as well as sensible heat. The thermal behavior of the phase change material during charging and discharging have been studied numerically, and analyzed under different conditions. Comparisons were made against experimental data for validation of the predictive model. The model fairly predicted experimental data obtained at various inlet conditions.

A numerical mathematical model has been developed to predict the thermal behavior of phase change material during thermal storage. The model includes the effects of various mechanisms of heat transfer such as conduction, convection as well as fusion of the phase change material. Water/Ice was used as a phase change material. The thermal behavior of the phase change material during cooling has been studied experimentally and analyzed under different conditions. Comparisons were made against experimental data for validation of the predictive model. The model fairly predicted experimental data obtained at various inlet conditions.
