Teaching & Research Interests: 

I am actively looking for UG/PG/ PhD students/ Post-docs from relevant branches for following research areas and even for noval and emerging research areas including bio-technology.

1. Numerical modelling and simulation of free radical polymerization in chaotic advection based tubular microreactor geometries.

Mostly numerical modelling and simulation based in the beginning. Development of mathematical framework to optimize microreactor geometry to enhance chaotic advection for different monomer-polymer systems under different operating conditions. Based on the simulation results, setup a pilot plant to validate the results. Then Scale Out instead of scale up to exploit the benefits of small radial dimensions for enhanced mixing.

2. Coiled flow inverter (CFI) microreactor hydrodynamics study on mixing.

Extension of Project-1 but under non-reaction conditions. Numerical study.

3. Separation of O2 and N2 from Air (SONA) Project

To create an efficient system for creating lab grade O2 (also medical grade) and N2 for university. Currently numerical modelling and simulation of process is going on. Based on the results, prototype system would be operated and tested.

4. Air Water Generator (AWG)

Extension of SONA Project (No.3). Additional benefit while separating O2 and N2 from air to generate drinking water from the same air. Currently numerical modelling and simulation of process is going on. Based on the results, prototype would be operated and tested.

5. Brackish/Sea Water to drinking water technology development

Working on developing and demonstrating and effective, efficient technology with a possibility of scale up to generate drinking water. Thermal pump based technology is under consideration. Currently literature review of process is going on. Based on the results, process will be designed.

6. Pulsating Heat Pipe (PHP) study

To optimize PHP for maximum heat removal rate conditions to make it applicable for various practical applications like heat removal in supercomputers etc. theoretical as well as numerical study is planned. Experimental setup is getting ready.

7. Hydrodynamics study of packed bed and model development

The study is to develop or improve existing models to predict the dry bed, wet bed pressure drop and hold up and loading point for different unstructured packing. Experimental setup will be added soon.

8. Study of Micromixing on fast chemical reactions

Modelling and simulation of monte-carlo based code in matlab is going on for a first order and higher order chemical reactions. Extension to CFD modelling and simulation and conducting actual wet experiment is underway.

9. Protein structure simulation based on gene mutation

Using Biovia, molecular dynamics simulation of protein structure generation and stable structure will be selected. Based on new structure, change in its interaction with other proteins will be studied.

10. Any Process Safety. Security related Project as proposed by candidate.

11. Fuel Cells, Design of new types of batteries etc.

The PhD student should be

  • Self-motivated,
  • Research oriented,
