“…The optimum parameters that achieve the best enhancement in heat transfer were the channel height of 17.5 mm, the wavy height of 2.5 mm, and the wave angle of 60 °. Abd Rabbo et al [36] numerically studied the hydrothermal characteristics of the trapezoidal corrugated channels. The Reynolds number range for air (100-1000), cutting edge ratio (0-0.6) and corrugation aspect ratio (0.2-0.5) were studied on the heat transfer and flow pattern.…”

The corrugation configuration played an important role in heat transfer enhancement in many engineering applications such as heat exchangers, microchannel heat sink, solar collectors, etc. The significance of the corrugation configuration is manifested in its ability to offer a larger heat transfer area more than a straight channel. Besides, the periodic interruption and redeveloping of the thermal boundary layer which is an important feature offered by corrugation is remarkably enhanced the heat transfer. The researchers were keen to take advantage of these features and develop them by manipulating geometrical parameters to obtain the optimal results. The current work aims to collect available research data, which focused on improving heat transfer in corrugated channels and identifying the most important factors affecting the performance of corrugated channels. Among the studied shapes of the various operating conditions of the corrugated channels, the researchers unanimously agreed that the trapezoidal shape of the corrugations gives the best thermal improvement with a reasonable pressure drop inside the channels.
