Experiments are conducted to investigate the heat transfer and pressure drop characteristics of corrugated tubes and rod baffles in a shell-and-tube heat exchanger. One of the effective techniques to improve heat transfer is to use corrugated tubes. This article investigates rod baffles with varied corrugation depths and corrugated tubes for (1 start). https://www.alarecre.com/NHL-Vegas-Golden-Knights-Black-Background-iPhone-14-Plus-Skin-p42149/
