HTRI has begun a research program dedicated to non-Newtonian flows. In order to discuss the plans for this research program, this webinar reviews the following items: the definition non-Newtonian fluids, the use apparent viscosity, focusing on power law fluids, how non-Newtonian flows affect pressure drop and heat transfer in heat exchangers...

HTRI conducted liquid-phase and phase-change experiments in a welded plate heat exchanger (WPHE) provided by Hisaka Works, Ltd. With the test plate pack installed vertically, cold fluid flowed horizontally, and steam condensed downward. We conducted single-phase and boiling tests using p-xylene as the test fluid, as well as boiling tests using...

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....

Component: Xphe Applicable to: All supported versions (versions 7.3 through 8.1) Date posted: 6 May 2020  Xphe, a module in Xchanger Suite, models plate-and-frame heat exchangers (PHEs) with rectangular plates. This TechTip provides a workaround for using Xphe to model plate-and-shell exchangers (PSHEs) with circular plates before HTRI develops a software...

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...
