Loop Heat Pipe based Novel Battery Thermal Management System for Hybrid EV/Electric Vehicle:
Loop Heat Pipe based Novel Battery Thermal Management System for Hybrid EV/Electric Vehicle:
A Loop Heat Pipe-based Battery Thermal Management System (BTMS) has been designed and developed for electric vehicles. Experimental investigations were carried out to assess the performance of the developed BTMS under varying charging and discharging rates at different ambient temperatures. Multi-evaporator-based BTMS systems were developed for battery modules of higher capacity. Our investigations confirmed that the developed BTMS is capable of maintaining battery module temperatures within the safe limit of 60 ºC, and the temperature difference (ΔT) across the module remains within 5 ºC.

Development of Numerical Models to Study Fluid Flow and Heat Transfer in Open Cell Foam:
Development of Numerical Models to Study Fluid Flow and Heat Transfer in Open Cell Foam:
The improved thermal-hydraulic properties of open cell foams, such as low overall density, high specific surface area, moderately high effective thermal conductivity, considerably high tortuous flow path, and allowing flow with comparatively lower pressure drop attracts researchers to investigate their performance for various applications. We focus on development of numerical models to calculate such effective thermos-mechanical properties of open cell foam.
Radiative Properties of Idealized Foam Structure
Radiative Properties of Idealized Foam Structure
A combined analytical-numerical model is developed to determine radiative properties of representative porous media using pore structure modelling along with radiation interaction with the solid matrix. The genetic algorithm (GA) code based on inverse method is developed and integrated to the FVM code. The obtained results of recurrence relationships are used in the FVM-GA code to determine extinction coefficient and scattering albedo of an equivalent homogeneous participating medium. Effects of solid reflectivity and pore density on the radiative properties of the porous media have been studied using the proposed mode

Radiative Properties of Actual Foam Structure
The numerical model is based on direct solution of the standard radiative transfer equation integrated with the inverse method based Genetic algorithm. The numerical model was developed in FORTRAN language where the standard radiative transfer equation, in a three dimensional porous domain was solved using the finite volume method. The actual structures of open cell foam were obtained using the CT scan images.

Forced Convection in Porous Foam
In order to estimate the volumetric heat transfer coefficient and thermal dispersion coefficient of the representative foam structure, pore level simulations were carried out in the commercial solver ANSYS-Fluent. The required mesh files were generated in ICEM tool. The employed numerical models are further utilized to determine the functional dependency of Nusslet number and dispersion coefficient on Reynolds number, Prandtl number, and porosity.
Development of Numerical Model for Cancer Treatment : Application to Radiation Therapy
Development of Numerical Model for Cancer Treatment : Application to Radiation Therapy
One of the important applications of the numerical modeling of heat transfer in porous media is laser-induced photothermal therapy where cancerous cells embedded inside biological tissue are destructed by inducing local hyperthermia using laser source. Since the successful destruction of the cancerous cells requires specified exposure time, a concrete understanding of light propagation inside the tissue phantom is essential.

Monte Carlo Ray Tracing based Statistical Model to Study Light-Tissue Interaction :
We developed a Monte Carlo ray tracing based statistical model to simulate radiation transport in biological tissue mimicking phantom. Both Snell’s law and Fresnel’s reflection are used to incorporate the optical interface treatment at the common interface of refractive index discontinuity. The effects of (i) nature of scattering, (ii) absorption and scattering coefficients, (iii) tissue layer thickness (iv) refractive index and (v) laser source on quantities such as reflectance, transmittance and fluence rate distribution are investigated. The developed model is further extended to investigate radiation transport in multi-layer tissue phantom with two blood vessels into consideration.

Combined Conduction-Radiation Model for Thermal Investigation of Laser Irradiated Tissue Phantom
Thermal investigation of two-dimensional tissue phantom, irradiated with short laser pulse, is carried out by importing the dosimetry data into Fourier conduction model. The multi-time scale approach, presented in the current study shows temporal variation of temperature at two distinct points, located at the top surface and at the centre of the tissue phantom. Two different numerical approaches, namely Monte Carlo technique and discrete ordinate method, tested in the present work show an excellent agreement.

Development of Numerical Model for Heat Transfer through Fabrics : Application to Fire Protective Clothing
Numerical simulations for heat transfer through fabric, exposed to fire is carried out as part of a study of the performance evaluation of thermal protective. The radiation modelling in air-gap is carried out using the finite volume method. The absorption of thermal radiation in fabric is modelled using Beer’s law. The temporal increase of temperature of the sensor is calculated with the lumped capacitance method. The simulated temperature of the sensor is compared with the experimental data and good agreement is found for smaller air gaps.
