Natural convection characteristics of power-law fluids over a heated vertical plate of variable surface conditions
Fluids such as molten plastics, polymers, pulps, foodstuffs or slurries exhibit non-Newtonian fluid behavior and are increasingly used in various manufacturing and processing industries. Determination of the friction and heat transfer characteristics of non-Newtonian fluids over heated surfaces is important for the design of industrial equipment working with this type of fluids. Steady free convection laminar boundary-layer flow along a heated vertical plate immersed in a quiescent power-law fluid is investigated. Two heating modes are considered by assuming that either surface temperature or heat flux has a power-law variation. Similarity solutions of the boundary-layer equations are obtained numerically for both heating conditions. The skin friction coefficient and Nusselt number are found to be higher in the prescribed temperature case for large Prandtl numbers and increase with the flow behavior index.
