Abstract
As an effective configuration for heat transfer enhancement, the corrugated tube is widely employed in engineering. It is very important to study the flow and heat transfer characteristics in corrugated tubes. The laminar heat transfer and flow characteristics in three corrugated tubes (φ = 19 mm, 25 mm, 32 mm) were investigated both experimentally and numerically. It has been found that the heat transfer of a corrugated tube is inferior to that of a plain tube in low Reynolds number region. With the increase of Reynolds number, the heat transfer of a corrugated tube is gradually enhanced and beyond a certain value of Reynolds number it has a higher heat transfer rate than that of a plain tube.
