  • GROUP 1: FLUID DYNAMICS


    Members: Dr. Vinod Gupta, Dr. Jogendra Kumar, Dr. Ruchika Atri

    Flow pattern and stability of a horizontal fluid layer heated from below and cooled from above is known as the Rayleigh-Benard convection. This convection mainly depends on the buoyancy force, caused by the temperature difference across the fluid layers; therefore it is also called the natural convection. The classical Rayleigh- Benard convection and its porous analog have been studied extensively due to its wide range of applications, such as in the prediction of ground water movement in aquifers, in the energy extraction process from geothermal reservoirs, petroleum industry, and underground diffusion of contaminants. Presently, we are working in the area of solutal convection, modulated boundaries, triple diffusion, Nanofluids, instability in cylinders.

  • GROUP 2: MATHEMATICAL MODELLING AND SCIENTIFIC COMPUTING


    Members: Prof. Naresh M. Chadha, Dr. Sandeep Sharma, Dr. Fateh Singh

    Mathematical modeling of infectious diseases is one of the most important research areas of the current time. An epidemic model enables us to understand and identify the conditions and parameters which are playing pivotal role in disease transmission. In recent past many realistic models pertaining to cancer, dengue, Ebola, SARS, HIV etc. has been formulated and analyzed. These epidemic models may consider a set of ordinary differential equations, partial differential equations, delay differential equations or stochastic differential equations. With the aid of computer algebra and theory of dynamical systems, these models provide key information about the disease dynamics which helps health agencies to reduce the burden of a particular epidemic.


  • GROUP 3: ADVANCED FUNCTIONAL SMART MATERIALS


    Members: Dr. K.K. Riana (Mentor), Dr. Surbhi Sachdev, Dr. Ravi Kumar Shukla, Dr. Pankaj Chamoli

    Research scholars: Mr. Prayas Singh, Miss Yogita, Miss Neha Duklan, Miss Priya Yadav

    Advanced Functional Smart Materials Laboratory has been established in the year 2019 and inaugurated by Honourable Chancellor and Vice-chancellor sir on 7th October 2019. The primary goal of this laboratory is to provide state-of-the-art facilities to in-campus and outside users from various universities, academia, industries and society. Our team is currently engaged in the cutting-edge research of soft materials and nanocolloids, green technologies and energy harvesting, purification and dye degradation, functional and high K dielectric materials, photocatalytic smart surfaces, sensors, energy storage devices, carbon nanomaterials and graphene for water purification and mesoscopic transport etc. In this laboratory, we have synthesis facilities such as spin coating unit, ultrasonic bath, hot air oven, centrifugal Unit, hydrothermal reactor, photocatalytic reactors, a complete facility for nanoparticles and nanocomposites/ nanocolloids synthesis. Apart from this, the available characterization facilities are UV-Visible spectrophotometer, Polarizing Optical Microscope, conductivity measurement, optical transmittance measurement, electro-optical and polarization measurements etc. Under this lab we are implementing two research sponsored projects viz (i) Lyotropic liquid crystalline materials for capacitive devices and as a water-free soft templates to develop nanostructures, SERB/DST Govt. of India (INR 39.3 Lakhs) and (ii) Synthesis of graphene-nano-composite for organic dyes removal, DIT University (INR 2 Lakhs). Two projects have been submitted to the CSIR, SERB.
