Thermal and thermohydraulic performance of wavy finned absorber solar air heater
Solar Energy, 2016Abstract In the present paper, the performance analysis of finned absorber solar air heater has been investigated analytically. The fluid channel is formed by two transversely positioned wavy fins attached on the absorber plate with bottom side thermally insulated and the top surface of absorber subjected to uniform heat flux.

Thermohydraulic performance of a novel curved serpentine coil
Physics of Fluids, 2020Conventional coil designs, such as helical and flat serpentine (FS) coils, are commonly employed for heat transfer applications due to their higher heat transfer performance and compactness. In the last few decades, chaotic coil designs have attracted the attention of a few researchers due to their superior thermohydraulic performance.

Abstract Three-dimensional heat transfer of nanofluids in microchannels with hydrophilic, hydrophobic and, superhydrophobic surfaces were studied using numerical simulation. For this purpose, Navier Stokes and energy equations were solved using the finite volume method. The flow Reynolds numbers were in the range of 40–500. Water/Al2O3 and Water/TiO2

A methodology is developed for performing statistical analysis of the uncertainties in thermohydraulic calculations on the basis of the idea of the GRS method. The coefficients, which are to be varied, in the semiempirical closure relations are determined for the RELAP5/MOD3.2 and MELCOR 1.8.3 codes; their distribution functions and variation ranges ...

Internal Groove Influenced Thermohydraulic Performance on an Air-Channel
Volume 1: Flow Manipulation and Active Control; Bio-Inspired Fluid Mechanics; Boundary Layer and High-Speed Flows; Fluids Engineering Education; Transport Phenomena in Energy Conversion and Mixing; Turbulent Flows; Vortex Dynamics; DNS/LES and Hybrid RANS/LES Methods; Fluid Structure Interaction; Fluid Dynamics of Wind Energy; Bubble, Droplet, and Aerosol Dynamics, 2018Internal fins, protrusions, and porous foams enhance the local convective heat transfer at the channel walls in the heat exchangers, electronic chips for cooling, and solar panels for cooling and heating by promoting the local turbulence in flow. However, the fluid pumping power in the channel suffers due to the blockage and high pressure drop caused ...

Thermohydraulic performance of packed-bed solar air heaters
Energy Conversion and Management, 1996Abstract This work is aimed at experimentally investigating the thermohydraulic performance characteristics of packed-bed solar air heaters. The thermohydraulic performance parameter called “effective efficiency” has been employed to express the net useful thermal energy gain, taking into account the equivalent thermal energy required to produce the ...
