Numerical Investigation of Forced Convection in a Horizontal Channel With a Built-In Triangular Prism

Forced convection heat transfer over horizontal triangular cylinder in cross flow

“…The correlation for the vertex facing the flow is given by Fig. 8(a) (18) and the one for the flat surface facing the flow is given by Fig. 8 Eq.…”

“…Their investigation showed that the time averaged Nusselt number can be described by a linear function of ln (Re) for Reynolds number range 50e200 and for zero Grashof number in air. Moreover, Abbassi et al [18] have investigated the structure of laminar flow (7) showing the side triangular length L and the test section square cross-section l such that the blockage ratio b ¼ L/l see text for details (all unit distances are in m). and heat transfer from a built-in triangular prism placed in a differentially heated channel.…”

Augmentation of heat transfer in a channel using a triangular prism

“…Abbassi et al [2] indicated that use of a prism could enhance the heat transfer in a channel. However their numerical study using FEM was limited to the laminar regime.…”

“…While the channel length was 32B, the location of the prism was maintained at x = 8B. This configuration was closer to the geometry of Abbassi et al [2] which was used as a benchmark for validation.…”

Heat Transfer Enhancement by Flow Control in a Rectangular Horizontal Channel

“…The results reveal that the transverse flow of air stream through the punched holes disturbs the air flow in the lower channel, enhancing the heat transfer on the under surface of fin. Reference [2] proved that the use of a triangular prism could enhance significantly the heat transfer in a channel. Reference [3] obtained numerically the rate of heat transfer enhancement in a channel due to the presence of a triangular element.…”
