RESUMO

Fully developed mixed convection between parallel plates for transient laminar water flow is analyzed by making use of a finite difference method, in the case of a temperature step applied at one wall. Results show that during the transient state, both prescribed constant pressure drop and bulk velocity cannot be imposed. Velocity profiles, friction forces at walls and characteristic times of the transient are investigated. A time-dependent selection criterion between forced, mixed and natural convection is also examined.
