A. Noume[1], C. Vasile[1], M. Risser[1]
[1]National Institute of Applied Science (INSA), Strasbourg, France

In automotive industry, regardless the type of engine we use, heating and air-conditioning is responsible for the highest energy consumption among all the auxiliary systems all over the year. For conventional vehicles with thermal engines, the heating of the internal space is easy ... Read More

Heat Transfer and Phase Transformation on Matrix Assisted Pulsed Laser Evaporation (MAPLE) of Biocompatible Thin Layers

E. Lacatus[1], G.C. Alecu[1], M.A. Sopronyi[2], A. Tudor[1]
[1]POLITEHNICA University of Bucharest, Bucharest, Romania
[2]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and ... Read More

Simulating Thermotherapeutic Response Induced by Thermal Padding for Treating Acute Injuries

J. Kantor[1], Y. Feng[1], C. Acosta[1], E. Massingill[1]
[1]University of Texas at San Antonio, San Antonio, TX, USA

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of ... Read More

Simulating HFIR Core Thermal Hydraulics Using 3D-2D Model Coupling

A. Travis[1], K. Ekici[1], J. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

A model utilizing interdimensional variable coupling is presented for simulating the thermal hydraulic interactions of the High Flux Isotope Reactor (HFIR) core at Oak Ridge National Laboratory (ORNL). The model’s domain consists of a three-dimensional fuel plate and a two-dimensional ... Read More

Computer-aided Design of the Heating Section of a Continuous Kheer (Rice Pudding)-making Machine

S. Kadam[1], T. Gulati[2], A. Datta[1]
[1]Indian Institute of Technology, Kharagpur, India
[2]Cornell University, Ithaca, NY, USA

Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which ... Read More

Modeling Flow and Deformation during Hot Air Puffing of Single Rice Kernels

T. Gulati[1], A. Datta[1]
[1]Cornell University, Ithaca, NY, USA

When rice is subjected to intense heating, it results in rapid evaporation of liquid water to vapor. As a consequence, large pressures are generated within the kernel in a span of 15s resulting in large volume changes causing the kernel to puff rapidly. Under suitable conditions, the ... Read More

Three-Dimensional (3D) Modeling of Heat and Mass Transfer during Microwave Drying of Potatoes

H. Zhu[1][2], T. Gulati[2], A. K. Datta[2], K. Huang[1]
[1]Institute of Applied Electromagnetics, Sichuan University, Chengdu, China
[2]Department of Biological and Environment Engineering, Cornell University, Ithaca, NY, USA

Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... Read More
