Unsteady free convection flow past a semi-infinite vertical plate with constant heat flux in water based nanofluids
The unsteady free convective flow of nanofluids past a semi-infinite vertical plate with uniform heat flux has been investigated numerically. An implicit finite difference technique of Crank-Nicolson scheme has been employed to solve the governing partial differential equations. Five different types...
