Debut of New Two-phase Flow Short Course

Integration of HTRI research experience and findings makes this course unique.

August 1, 2016

HTRI continues to investigate the impact of two-phase flow on heat exchanger designs, and a new short course showcases our research-based perspective on two-phase flow. If you are an engineer who works in two-phase heat exchanger or process piping applications, then you will be interested in this exciting addition to the HTRI training program.

Instructor Siddharth Talapatra

The debut offering of the Two-phase Flow Short Course is set for Thursday, September 22, 2016 in conjunction with the 2016 Global Conference and Annual Meeting of Stockholders in Seattle, Washington, USA. Siddharth Talapatra, HTRI Research Engineer, will be the course instructor.

Sid will use an application-oriented approach to explain the fundamentals of two-phase flow, work through key models useful for engineering analyses, and wherever possible, introduce videos to illustrate two-phase phenomena. Throughout the course, Sid will introduce case studies to reinforce the implications of two-phase modeling assumptions. At the end of the course, you will have a set of tools and recommendations to help you with your day-to-day engineering challenges related to two-phase flow.


Academy Award-winning director, screenwriter, and producer Barry Levinson extended upon the old adage that “if a picture is worth a thousand words, then a video is worth a million.” With the help of the transparent shell-and-tube exchanger (TSTX), part of the Multipurpose Visualization Unit (MVU), in HTRI’s multi-million dollar research facility, we have the ability to visualize various two-phase flow phenomena.

The integration of HTRI research experience and findings make this course unique and relevant to the process industry. Key topics include:

  • Tubeside and shellside flow regimes, and their dependence on geometry (e.g., pipe size, inclination, baffle spacing)
  • Static, frictional, and momentum pressure drop: Basics and important correlations
  • The impact of service type (boiling, condensation, adiabatic) on two-phase distribution and pressure drop
