Investigation on heat transfer characteristics of molten salt in a shell-and-tube heat exchanger

Numerical and experimental study on heat transfer and flow features of representative molten salts for energy applications in turbulent tube flow

“…This is mainly due to the fast developments of CSP and nuclear technologies, where reliable heat transfer data and correlations with high accuracies are highly desired for the designs of heat transfer devices. From 2009 to now, the heat transfer performance of two liquid salts has been investigated by testing some shell-and-tube heat exchangers(STHX) when the salt flows in the tubes, where Hitec [13,[22][23][24][25][26] and LiNO3 [22,27,28] were employed.…”

Optimum Design of Shell and Tube Heat Exchangers using Modified Kinetic Gas Molecule Optimizer for the use of Low Temperature in Organic Rankine Cycles

“…Where, is denoted as the fraction of baffle window tube, which is evaluated by categorizing the average window tube number by the total tube number . The similar applies in the tube-to-baffle and shell-to-baffle leakage areas are calculated by using the equations (10) and (11).…”

“…The STHEs is combined with ORC for preventing liquid flow inside the tubes to mix with the fluids outside the tubes. Many research works are done to improve the electricity production efficiency in ORCs by optimizing the cycle parameters like pressures, temperatures and mass flow rates [10][11]. Recently, several systems are developed in STHEs to improve the electricity production efficiency such asentransy theory with genetic algorithm [12], genetic algorithm [13][14], non-dominated sorting genetic algorithm [15].However, the existing algorithms have a few own limitations like heat-source cooling efficiency is limited and the amount of heat losses from the outer surface of the heat exchanger to the surroundings is excess.In order to address the above-mentioned problems, an efficient technique is developed for electricity generation from the combined ORCs and STHEs.…”
