Heat transfer and pressure loss in narrow channels with corrugated walls

The effects of geometrical parameters of a corrugated channel with in out-of-phase arrangement

“…Elshafei et al [22,23] studied experimentally forced convection heat transfer and pressure drop characteristics of flow in corrugated channels. The results show that the average heat transfer coefficient and pressure drop enhanced by a factor of 2.6 up to 3.2 and 1.9 to 2.6 relative to those for parallel plate channel, respectively, depending upon the spacing and phase shift.…”

Augmentation of Fluid Flow and Heat Transfer Characteristics in corrugated Channel: A Review Study

“…The thermal hydraulic performance of the corrugated channels was experimentally tested by Elshafei et al [9] On a band of air Reynolds range of (3220-9420), experiments were performed on channels with constant corrugation ratio (2Amplitude/waviness = 0.2) under uniform wall temperature. Three wavy channels (0 °, 90 °, and 180 °) were considered to be different distances.…”

“…The coefficients of heat transfer gets from the channel with the corrugated wall are better than that containing the smooth surface Elshafei et al [9] 2008 wavy (0 °, 90 °, and 180 ° )…”

Three dimensional numerical investigations on the heat transfer enhancement in a triangular facing step channels using nanofluid

“…Additionally, the separation point of the flow was observed to be highly dependent on the channel height, while the reattachment point of the flow was independent of it. The flow characteristics and heat transfer of air flow in the corrugated channels under the conditions of constant surface temperature and Re ranging from 3220 to 9420 were studied experimentally by Elshafei et al [15,16]. The results indicated the influence of channel spacing variations on the heat transfer and the friction factor was dependent than the phase shift variation especially at high Re.…”
