Developing Turbulent Forced Convection in Two-Dimensional Duct
Developing turbulent forced convection ﬂow in a two-dimensional duct is simulated for Reynolds numbers ranging from 4560 to 12,000. Simultaneously developing velocity and temperature distributions are reported by treating the inlet ﬂow as isothermal with uniform velocity proﬁle. The walls are supplied with uniform heat ﬂux. Distributions of the streamwise and the transverse velocity components exhibit a maximum near the walls, but not at the center of the duct, in the developing region of the ﬂow. The friction coefﬁcient and the Nusselt number do not reach the fully developed values monotonously, and a minimum in their distributions appears in the developing region. Some results are compared with the available data, and very favorable comparisons are obtained.
