WebJan 1, 2024 · The disc and doughnut baffles in the shell and tube heat exchangers can be superior alternatives over the conventional segmental baffles. In this paper, CFD modeling and analysis were carried out ... WebThis report introduces new methods for analyzing and rating a disk-and-doughnut baffled heat exchanger. Using three-dimensional computational fluid dynamics (CFD) simulations, we describe the exchanger’s thermal-hydraulic performance in detail. Validated CFD results enable us to perform a high-resolution stream analysis through the exchanger ...
