Scientific Achievements:

1). Recently we are able to relate fin heat transfer with the governing parameters by a very simple linear line, which will be very much useful for the designers of heat exchanger for a flow in the laminar range. Although this relation is obtained from the Computational method, but our results validate the experimental results within less than 6%. Here our group are Dr. Maibam Romio Singh and myself. 

(2). Finding effective heat transfer from variable fin-height (Numerically as well as Experimentally) by our group (Dr. Kankan Kishore Pathak, Dr. Maibam Romio Singh, Prof. Biplab Das, Dr. Debayan DasGupta, Prof.(Dr.) Pradip Lingfa and myself). It also requires lesser materials and hence it has double benefits.

(3). Our Experimental work on (1/10) th scale pressurised Nuclear Power Reactor Vessel failure and its management to cool the reactor vessel through gap cooling finds a special space in the European Union and it is very much useful for the safety management of present pressurised nuclear reactors. Our group consisted of the European Union and the USA.

(4). My Ph.D. work (both Experimental and Numerical) on Multi-bubble Sonoluminescence(MBSL) and a Few bubbles Sonoluminescence (FBSL) is one of the most fundamental works in sonoluminescence.
