Xspe® is an incremental program that lets you quickly and easily predict the thermal-hydraulic performance of Type I (i.e., spiral-spiral flow) single-phase spiral plate exchangers. This webinar gives a brief overview of the basic geometry of spiral exchangers, highlights the benefits of this exchanger type, such as the self-cleaning mechanism and true...

Two important considerations in heat exchanger design and analysis with Xchanger Suite are defining a heat exchanger’s geometry and specifying fluid properties. This webinar focuses on fluid property specification. We will provide an overview of the available options in Xchanger Suite, illustrate these options using simple examples, and discuss HTRI’s recommendations and guidelines. ...

HTRI collected falling film evaporation data for two pure components and three mixtures in a vertical tube. Current falling film methods in Xist® 8.2 underpredict most of the measured heat transfer coefficients. Based on the latest data, we have improved our heat transfer methods, including a vapor-shear enhancement factor, a new mixture correction factor...

Siddharth Talapatra, Group Lead, Research   Most of us, engineers and non-engineers alike, tend to think we can tell a "solid" from a "fluid". But how do we define the characteristic difference? Most physics textbooks use the concepts of "elastic/plastic deformation" to define solids and "viscous deformation" to define fluids. In...

HTRI collected data for falling film evaporation in a vertical tube using five test fluids. This report discusses available pressure drop methods and correlations for intube falling film evaporators and investigates correlations for liquid film thickness and void fraction. The report also documents an improved pressure drop method based on the...
