Numerical analysis of heat transfer and fluid flow through the twisted square duct (TSD): Nanofluid as working fluid

A study on entropy generation and heat transfer in a magnetohydrodynamic flow of a couple‐stress fluid through a thermal nonequilibrium vertical porous channel

“…An empirical approach is carried out by Mikkola et al 5 to check how the properties of nanoparticles affect the heat transfer of nanofluids. The heat transfer phenomenon in a steady laminar flow inside the twisted duct is numerically studied by Mahato et al, 6 and they observed enhanced heat transfer rate for the least twist ratio parameter.…”

A Comparison of Circular Duct and Real Hexagonal Duct Results Using Hydraulic Diameter

“…Hexagonal-shaped cross-sectional channels are generally encountered in nuclear engineering applications, waste heat recovery, cooling systems of electronic devices and lamella type compact heat exchangers used in many industries such as paper, alcohol, petrochemical and food [3]. Literature review shows that laminar [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and turbulent [19][20][21][22][23][24][25][26][27][28][29] heat transfer and fluid flow in hexagonal channels are examined by some researchers. Rokni and Gatski [19] predicted turbulent heat transfer and turbulent fluid flow in non-circular channels including rectangular cross-sectional duct with aspect ratio 2.…”

“…Gunes et al [27] performed a numerical study to examine the heat transfer and fluid flow in a tube with hexagonal cross-sectioned coiled wire for the Reynolds number range of 5000Re17,000. Mahato et al [28] conducted a numerical study to investigate the turbulent flow and heat transfer in hexagonal twisted duct. Turbulent heat transfer and fluid flow in a hexagonal duct with twisted-tape inserts were examined experimentally by Yadav et al [29].…”
