Multiphysics Modeling of a Minimally Invasive Tissue Ablation Methodology

J. S. Crompton [1], J. Thomas [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Necrosis of human tissue can typically be obtained by exposure to temperatures below 40°C or above +50°C. However, inherent variability in tissue properties, the complexity of tissue response and dissipation of thermal energy by local perfusion or blood flow can make the development of ... Mehr lesen

Radio Frequency (RF) Thawing Irregular Shape Frozen Beef — A Computational Study

Yang Jiao [1], Yulin Li [1], Yifen Wang [1]
[1] Shanghai Ocean University, Engineering Research Center of Food Thermal-processing Technology, Shanghai, China

Imported beef often comes in halves or quarters of frozen bodies, which are irregular. Radio frequency (RF) heating can reduce processing time and minimize nutritional damage when applied in meat thawing. Because of its large penetration depth and high heating rate, RF thawing has a ... Mehr lesen

Mathematical Modelling of Evaporation of Water Using Steam–Unitary Model Analysis

D. Rakshit [1], S. Ramanathan [2],
[1] Indian Institute of Technology Delhi, India
[2]Centre for Science and Environment, New Delhi, India

Multiple effect evaporators use steam of temperature 120-200°C as a source of heat to evaporate water from solutions. Multiple effect evaporators are widely used by the food, desalination and wastewater treatment industry. In the present study as a proof of concept, multi-physics ... Mehr lesen
