“…mixed convection heat transfer from Al2O3-water nanofluid in W-shaped, copper tube cause the rate of heat transfer coefficient improved with Reynolds number for average wall temperatures of 50 and 60ºC. Magneto hydrodynamic nanofluid flow between two parallel analyzed and results showed concentration of nanofluid diminishes when Brownian movement increments whereas it increases with expands of thermophoretic parameter [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Gupta et al [21] examined magneto convection in a nanofluid.…”
