“…The efficiency of hexagonal fins may be determined based on an equivalent outer radius of a circular fin with an efficiency corresponding to the efficiency of a hexagonal fin. The equivalent radius was defined by Equation (15). Further details of the overall product air-side surface efficiency calculation are shown in Table 3.…”

“…Due to an optimized air and water flow arrangement, the wet-bulb efficiency of the proposed evaporative cooler was increased by 29.3% and the coefficient of performance (COP) was increased by 34.6%, compared to the commercial unit of the same capacity. Al-Abbasi and Al-Alawi [15] analyzed numerically the performance of the IEC system with regeneration. In order to obtain higher accuracy, the CFD technique was applied.…”

In the present work, the effects of different operating parameters on the performance of a gravity-assisted heat pipe-based indirect evaporative cooler (GAHP-based IEC) were investigated. The aim of the theoretical study is to evaluate accurately the cooling performance indicators, such as the coefficient of performance (COP), wet bulb effectiveness, and cooling capacity. To predict the effectiveness of the air cooler under a variety of conditions, the comprehensive calculation method was adopted. A mathematical model was developed to simulate numerically the heat and mass transfer processes. The mathematical model was validated adequately using experimental data from the literature. Based on the conducted numerical simulations, the most favorable ranges of operating conditions for the GAHP-based IEC were established. Moreover, the conducted studies could contribute to the further development of novel evaporative cooling systems employing gravity-assisted heat pipes as efficient equipment for transferring heat.

“…Evaporative cooling units can be used in a residential area, business buildings, and data center cooling. Evaporative cooling unit has two distinguished systems; Direct Evaporative Cooling unit (DEC) and indirect evaporative cooling system (IEC) [1][2][3]. An indirect evaporative cooler (IEC) is an energy-efficient cooling device which has been widely used to cool the air or other fluids [4][5][6][7].…”

Due to the lower energy consumption in the evaporative cooling, it is the subject of numerous studies. Evaporative cooling considers a green cooling system which does not require any chemical reaction and does not depend on the hazardous material. The present study mainly focused on parametric analysis of an indirect evaporative cooling system using the computational fluid dynamics method. The numerical simulation of an indirect evaporative cooling system was carried out using ANSYS Fluent 18.2. The effects of the water inlet velocity, air inlet velocity, coil diameters (d c ) and the number of the heat exchanger copper coils were numerically investigated. The flow was considered as threedimensional, turbulent, and incompressible. The results indicated that the increment of the coil diameter and water inlet velocity had a positive effect on the performance of the indirect evaporative cooling system. The maximum water outlet temperature was obtained at 285.05 K for the water inlet velocity of 0.5 m/s. Moreover, the saturation efficiency is decreased by increasing air inlet velocity. On the other hand, saturation efficiency was increased at all air inlet velocities by increasing the coil diameter.
