Tag: PLATE HEAT EXCHANGER

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...

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....

This report proposes an improved condensation heat transfer method for corrugated channels in plate heat exchangers, based on n-pentane condensation data collected in a welded plate heat exchanger. The generalized method is applicable to all corrugated channels in different types of plate heat exchangers, such as plate-and-frame and  plate-and-shell heat exchangers. ...

HTRI conducted water-to-water liquid thermal performance testing in a plate-and-shell heat exchanger (PSHE) provided by Vahterus Oy. This report discusses the test setup and data collection, summarizes the heat transfer and pressure drop results, and correlates the test data against current HTRI methods. Since HTRI currently has limited data related to...

HTRI experimentally evaluated the thermal-hydraulic performance of a water-water plate-and-shell heat exchanger at the Research & Technology Center and then used the results to calibrate a solution approach through computational fluid dynamics. The tortuous flow paths through the corrugated channels of the plate pack were modeled effectively using porous media. Inertial resistance...

HTRI gathered experimental data for a plate-and-shell exchanger at the Research & Technology Center (RTC). These data provided the opportunity for HTRI to extend its CFD simulation experience to plate heat exchanger types. The results provide additional insights about the flow distribution and port pressure drops. In this webinar, we discuss...

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...

Computational fluid dynamics (CFD) analysis was used to calculate the nozzle pressure drop K-values for spiral plate heat exchangers. Results of this analysis resolved the discrepancy between K-values from the Minton method and in PHE-11. The K-values from PHE-11 compared better with the CFD results in the region of Reynolds numbers...
