TechTip: Modeling Plate-and-Shell Heat Exchangers using Xphe

July 29, 2020

This webinar briefly reviews HTRI research on plate-and-frame heat exchangers and plate-and-shell heat exchangers (PSHEs), focusing on the geometry differences and similarities between the two types. Xphe® is a module in Xchanger Suite® for modeling plate-and-frame heat exchangers. Using an example case, we will discuss how to use Xphe to model a PSHE. Additionally, we identify the key...

Advancing HTRI's plate heat exchanger technology

October 16, 2018

LiDong Huang, Principal Engineer, Experimental Research Many different designs of plate heat exchangers (PHEs) exist for different heat transfer processes. Most PHEs are formed by corrugated plates, which are often spaced by rubber sealing gaskets or welded together to form hot and cold channels. Plate shapes and fluid distribution vary for...

PHE-18-TR Shellside Boiling Tests in Plate-and-shell Heat Exchanger

July 10, 2018

HTRI collected flow boiling data using a plate-and-shell heat exchanger (PSHE) provided by Vahterus Oy. In the exchanger, steam condensed on the plate side, and process fluids—pure n-pentane and a mixture of n-pentane and p-xylene—boiled on the shell side. This report discusses the data and analysis, including evaluations using Xphe® 7.3.1....

Research Update: Condensation in Welded Plate Exchangers

January 16, 2017

Plate heat exchangers (PHEs) are well suited for applications that require compactness, low weight, and high efficiency. Traditional gasket-type PHEs are limited to a low range of pressures and temperatures. When operating pressures and temperatures exceed the range of a traditional gasket PHE, a welded-plate design is sometimes used. This webinar...
