CHFIC - 2018 A national conference on Critical Heat Flux for boiling is to be organized jointly by Indian Institute of Technology, BHU and Indian Institute of Technology, Bombay. The conference would be held at IIT BHU during Dec 22-23, 2018.

The aim of conference is to understand and revisit the critical heat flux phenomena by eminent scientists active in this area of heat transfer. This meeting is expected to act as a platoform to deliver and interact on current trends of research in boiling heat transfer and its applications into real life problems concerned with science, technology and society with their solutions. The conference is also open to student community to showcase and sensitize the heat transfer community with their research findings.

Scope of the Conference Critical Heat Flux (CHF) was first discovered by Nukiyama in the year 1934. The CHF phenomenon limits the maximum power output of thermal plants and nuclear reactors, and hence needs to be understood adequately. Needless to say, CHF has an important bearing on both safety as well as economics of power plants. CHF manifests itself in two different phenomenological forms viz., DNB(Departure from Nucleate Boiling) and LFD (Liquid Film Dryout) depending on the operating conditions (BWRs, PWRs). Researchers have performed numerous experiments under various geometrical and operating conditions to understand the trend of CHF. In this process, AECL has developed CHF Look up Table using the world data. However, due to strong dependency of CHF on the geometrical and operating conditions, plant venders depend heavily on experiments to establish the safety margins. In the past few decades, a lot of research has undergone with the aim to model the CHF from first principles. The present mechanistic models are still in the development process to attain the level of maturity so as to substitute the expensive experimentations.

In view of these challenges, the theme of the conference is focused to bring out the state of the art in modeling and experimentation for CHF and identify the avenues for future developments in this area. The conference shall have keynote talks by experts and presentations on following topics:

* Experiments on CHF

* Modeling of dryout and DNB

* Current approaches for CHF evaluation in the system codes

* Application to Industries (Nuclear, Chemical, Process, etc.)

* Sensors development for multiphase flow

The conference theme is targeted to students/scientists/engineers engaged in the thermal design and safety analysis of nuclear systems and process industries as well as research fraternities of academic institutes carrying out experiments and modeling dryout /DNB. Sharing the experiences and knowledge base would mutually benefit the participants.
