Abstract

Process Equipment and Design (PED) laboratory at Cryogenic Engineering Center (CEC), IIT-Kharagpur has been extensively focused on the research activities related to cryogenic processes and related equipments. The research is being carried out in the fields of cryogenic turbo-machinery, cryogenic storage, transfer, two-phase flow, and process simulation etc. Cryogenic turbo-expander for small scale experiments, using air, nitrogen and helium as a working fluid, has been designed, fabricated and tested for the centrifugal stresses along with the investigation of performance of using mean line analysis.  The lessons learnt and planned future tasks related to the cryogenic turbo-machinery will be discussed during the talk.
PED lab is also involved in investigating, transfer and two-phase related problems in the cryogenic domain using advanced software like Flownex, GFSSP, Ansys, and Openfoam etc. Examinations are being carried out regarding chilled down of cryogenic transfer lines, hammering effects, etc. Single and multiple bubble studies are being conducted via direct numerical simulation to propose potential benefits in biomedical and heavy engineering. The talk will cover the major issues faced and resolving steps taken during the above activities.
In the field of cryogenic process simulation and equipment design, various studies have been conducted at PED lab. There are many research activities including the customization of the commercial process simulators like Aspen has been conducted and issues with the commercial process simulators have been pointed out. PED lab has also highlighted what features should a cryogenic process simulator equipped with. In this regard, PED lab is working on the development of a cryogenic process simulator, which will be able to cater the needs of the academia and industry regarding cryogenic process simulations. The talk will focus of the research being carried out and the future activities related to the cryogenic process simulator development.
The talk will also cover the different aspects of cryogenic systems, and may be useful to the audience from different disciplines e.g. Mechanical, Chemical, Process etc.
