  • Historic cold weather causing
    intermittent disruptions in HTRI operations

    February 15, 2021
    A historic cold weather event has affected our Corporate Headquarters in Navasota, Texas, USA, as well as many of our staff that live in the surrounding area. We are experiencing some temporary disruptions in operations due to intermittent power outages and unreliable internet connectivity. Travel is also unsafe. During this weather event: Our...

  • Research Update: 2020 - Year in HTRI Research

    February 09, 2021
    After summarizing the results from HTRI Research over the past year, this webinar provides insights into how these results improve our technology and its use by HTRI members. Topics include prediction of hot air recirculation for air coolers, development of new non-Newtonian heat transfer correlations, modification of tubeside falling film heat...

  • Getting Started: Building Your First Case in Xspe

    January 13, 2021
    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...

  • A Look Back at 2020

    December 23, 2020
    Dear Members, Business Collaborators, Former Staff, and Vendors all over the world, Please join us for a few minutes of reflection on this past year. In January 2020 we had no idea of the upheaval soon to come, but 2020 clearly has been a year unlike any other in recent history....

  • Getting Started: Specifying Fluid Properties in Xchanger Suite

    November 19, 2020
    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. ...

  • BT-42 Improved heat transfer methods for tubeside falling film evaporators

    November 17, 2020
    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...

  • Non-Newtonian fluids: From concepts to modeling

    November 09, 2020
    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...

  • FY 2020 Report to Stockholders

    October 20, 2020
    COVID-19 continues to impact everyone to some degree. The health and safety of you and our staff remains a top priority, prompting flexibility and changes in business operations. We cannot come together to deliver the HTRI Stockholders Report in-person; however, we want our members to still receive the annual update on...

  • BT-41 Pressure drop method for tubeside falling film evaporators

    October 19, 2020
    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...
