摘要:
The pressure drop on the gas-side of an experimental shell-and-tube heat exchanger consisting of a bundle of seven tubes with roughened outer walls inside a smooth hexagonal shell is described. Based on the test results, an analytical method for predicting pressure drop in a heat exchanger with partially smooth and roughened surfaces was developed using the annulus flow model.
