The present numerical model takes into account available work losses, i.e. irreversibilities, due to heat transfer and frictional pressure drops of heat exchangers.
The main design development strategies were regulating the flow area ratio and offsetting plates in order to balance the heat transfer and pressure drop of the heat exchanger.
This study analyzes five experimental factors (flow depth, ratio of fin pitch and fin thickness, tube pitch, number of louvers and angle of louver) affecting the heat transfer and pressure drop of a heat exchanger with corrugated louvered fins using the Taguchi method.
For heat sinks in parallel, pressure drop of the heat sink in subcooled boiling changed and eventually resulted in uneven mass flux distribution, where flow rate of the heat sink became less than 0.4 L/min and the total volume flow rate stabilized at 0.8 L/min.
The review of available works display that the heat transfer and pressure drop characteristics of heat exchangers using scCO2 as working fluid rely on many parameters such as tube shape and size, mass flux, inlet temperature and pressure, type of process (heating or cooling) etc.
The total pressure drop of the heat recovery system is 0.74 Pa.
Fire-retardant investigation (cone calorimeter test) revealed that EP nanocomposite with 2 wt% GO@MCM-41 possessed a 40.0% drop of peak heat release rate (pHRR) and suppressed smoke production relative to EP/GO.
The results of the 1-D model enable the construction of surrogate functions for the thermal resistance and the pressure drop of the heat sink, which are considered as the objective functions for the multi-objective optimization through a genetic algorithm that leads to the optimal geometric parameters.
Each tendon piece was submerged in a drop of 50% heat in-activated foetal bovine serum (FBS) (Biosera, Ringmer, United Kingdom) /DMEM-F12 containing 1% penicillin/streptomycin (Sigma, Poole, United Kingdom) in order to encourage cell migration while reducing infection.
The effects of vortex generators on heat transfer and pressure drop of a novel heat exchanger are investigated using computational fluid dynamics (CFD) method.
