Buoyancy effects on heat, mass and momentum transfer during the melting of a horizontal ice sheet above fresh or saline water flowing at laminar Reynolds numbers
A finite difference steady state two-dimensional analysis is made for the combined convection heat, mass and momentum transfer phenomena for pure or saline (Sₒₒ = 5‰ and 35‰) water flowing at laminar Reynolds numbers below a semi-infinite horizontal melting sheet of pure ice. All fluid properties, e...

All fluid properties, except density in the body forces terms of the momentum equation, are assumed to be constant. -- For the fresh water case, a 51 by 21 grid is used for the computer analysis and downstream boundary conditions are applied at a distance of 1.731 m from the leading edge. For Sₒₒ = 5‰ and 35‰ 52 by 52 and 68 by 65 grids are used respectively and downstream boundary conditions are applied at a distance of 1.021 m.
