Fully developed duct flow uniform temperature, laminar

If the solution procedure is carried through as outlined above, the following is obtained for fully developed laminar flow through a plane duct with uniform wall temperature ... [Pg.179]

Water flows in a rectangular 5 mm x 10 mm duct with a mean bulk temperature of 20°C. If the duct wall is kept at a uniform temperature of 40°C and if fully developed laminar flow is assumed to exist, find the heat transfer rate per unit length of the duct. [Pg.222]

Consider a series of rectangular channels of width W, and height H, all with the same cross-sectional area whose walls are kept at a uniform temperature. The flow in these ducts can be assumed to be fully developed and laminar. [Pg.222]

Heat Transfer on Walls With Uniform Temperature. For this boundary condition, denoted as , temperature distribution in a circular duct for fully developed laminar flow in the absence of flow work, thermal energy sources, and fluid axial conduction has been solved by Bhatti [3] and presented by Shah and Bhatti [2], as follows ...

Uniform Heat Flux at Each Wall. When the heat fluxes on the two walls of parallel plate ducts are equal, qZi = q U, the temperature distribution of fully developed laminar flow is given by ... [Pg.362]

Uniform Temperature at One Wall and Uniform Heat Flux at the Other. When the two walls of a parallel plate duct are subject to a thermal boundary condition such as uniform temperature at one wall and uniform heat flux at the other, the Nusselt numbers for fully developed laminar flow for qZ = 0 and q"w 0 are determined to be ...
