Effect of perforation shape and porosity on effective thermal conductivity of matrix heat exchanger plates

FHD and MHD effects of Fe3O4-water magnetic nanofluid on the enhancement of overall heat transfer coefficient of a heat exchanger

“…Addition of nanomaterials to base fluids, which results in nanofluids, is a new and exciting method for producing higher heat transfer rate and thermal efficiency [8][9][10][11][12][13][14][15]. Therefore, in the past decade, many studies were done on thermophysical properties of nanofluids and uses of nanofluids in enhancement of heat transfer performance-especially thermal conductivity-of conventional heat transfer fluids such as water [16][17][18][19][20][21][22][23][24][25][26]. Magnetic nanofluids are a particular group of nanofluids containing magnetized nanoparticles typically called magnetite [27].…”
