The effects in terms of heat flux, working fluid mass flux, heat source temperature, and super-heated degree at the outlet of the BPHE were investigated.
For Figure 4, the cooling rate in the stable film boiling regime increases with the increase in working fluid mass flux.
The area averaged heat transfer coefficient was found to be a strong function of working fluid mass flux and array geometrical aspect ratio.
The influence of three operating parameters, i.e., input heat flux, working fluid, and filling ratio, on the performance of the engine was characterized.
The inlet working fluid mass flux is 348 kg/m2s with an input heat power of 200 W. Figure 12a reveals that the local heat transfer coefficient increases with silver nanoparticles suspended in deionized water.
According to the thermodynamic analysis, a very simple expression for the optimal Reynolds number for the double sine duct as a function of mass flow rate, wall heat flux, working fluid and geometric dimensions is proposed.
In this work, flux decline during crossflow ultrafiltration of macromolecules with ceramic membranes has been modeled using artificial neural networks.
The current study indicated that the heat transfer coefficients show great sensitivity to heat flux and working fluid mass flow rate.
Water was used as the working fluid with mass flux, based on the mean cross section area, ranging from 99 to 297 kg/m2 s.
A semi-transparent liquid, namely ethanol, was used as the working fluid, with a mass flux of 20.3 kg/m2s and heat flux range of 3.1 244.1 kW/m2.
