Impact of Different Modeling Approaches in Field Focusing Predictions of Hyperthermia Cancer Therapy

R. Gaffoglio[1], G. Vecchi[2], M. Righero[1], G. Giordanengo[1], M. Zucchi[2]
[1]LINKS Foundation, Italy
[2]Politecnico di Torino, Italy

The hyperthermia therapy (HT), i.e. an increase of the body tissues temperature to 39-43 °C caused by the exposure to non-ionizing electromagnetic radiation (like radiofrequency or microwaves), has been demonstrated to sensitize tumours to radiotherapy and chemotherapy (i.e. cancer ... Read More

Iterative Caloric Effects Modelling Using COMSOL Multiphysics® and the LiveLink™ for MATLAB®

A. Lopes[1], T. Santos[1], D. Silva[1], C. Roque[1], J. Amaral[1], V. Costa[1], V. Amaral[1]
[1]Universidade de Aveiro, Portugal

Scientists and engineers have been designing and developing computational tools for the numerical simulation of heat transfer processes involving non-conventional heating or cooling effects for several years. Caloric effects rely on temperature variations upon external stimuli, e.g. ... Read More

Simulation of Silver Evaporation for A Knudsen Effusion Experiment Under Zero Gravity

D. Henriques[1], H. Fritze[2], M. Schulz[2], T. Markus[1]
[1]Hochschule Mannheim, Germany
[2]TU Clausthal, Germany

Material constants are required to develop new materials for the aerospace, automotive and energy industries. With these highly accurate experimentally determined data, complex metallurgical melting processes can be simulated later, for example. The microstructure of the new alloy can be ... Read More

Presumed Beta-PDF Model for the Prediction of the NOx and CO Emissions in Combustion Chambers

A. Martínez González[1], P. Nakate[1], D. Lahaye[1]
[1]Delft University of Technology, Netherlands

Optimization by means of computational tools has been stunningly useful for different industrial furnaces. However, the complexity of the equations, the wide range of characteristic times in the process, and the difficulty to extract precise enough data to model a combustion chamber ... Read More

From the Laser Parameters to the Tribological Properties with COMSOL Multiphysics®

V. Bruyere[1], J. Wheeler[1], P. Namy[1]
[1]SIMTEC, France

Whereas the physic models of fluid lubrication should be able to provide quantitative predictions to industrial problems, it is somehow demanding to provide the input data to feed these high-level equation systems. The operating conditions are generally available, and the material ... Read More

Optimization of the acoustic pressure distribution inside a freeze drying chamber

Numerical Optimization of the Ultrasonic Cleaning Technique for Pipelines

H. Lais[1], J. Kanfoud[1], T. Gan[2]
[1]Brunel Innovation Centre, United Kingdom
[2]TWI Ltd., United Kingdom

Fouling accumulation in pipelines is a known problem in industry which is currently treated by mechanical, hydraulic and chemical means. Each requiring a halt in the production to carry out the procedure. Industry requires a method that is non-invasive and can be used in-situ, Ultrasonic ... Read More

Coupled Electromagnetic-Thermal Model of a Superconducting Motor

[1]University of Applied Sciences Augsburg, Germany
[2]Comsol Multiphysics GmbH, Germany

Water transport in the public sewer system is often based on open channel flow, e.g. in a DN100 drainage pipe. Especially for low flow rates of less than 10 mL/s and with water levels of less than 4 mm, flow sensors are hardly available. In order to enable the measuring of very low ... Read More
