A Model to Simulate Laser Ablation in Tumor Using Dynamic Photothermal Coupling Interaction Model

Zhifang Li [1], Xiyang Zhang [1],
[1] College of Photonic and Electronic Engineering, Fujian Normal University, Fuzhou, China

Laser immunotherapy (LIT) was developed to treat late-stage, metastatic cancers through local laser irradiation and immunological stimulation. In ILIT, the photothermal effect induces immune responses by destroying and interrupting tumor cells through temperature elevation in target ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る
