Simulation of a Piezoelectric Catheter-Based Acoustic Ablation Device

M. Gobran¹, N.Elabbasi², J. Ransley²
¹Worcester Polytechnic Institute, Worcester, MA, USA
²Veryst Engineering LLC., Needham, MA, USA

Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... En savoir plus

3D Modeling and Analysis of a Mock-up Ironless Stator Design for Electrical Machines

T. Aravindakshan¹, Dr. P. Masson²
¹Florida Institute of Technology, Melbourne, FL, USA
²AML Superconductivity and Magnetics, Melbourne, FL, USA

With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded which results in the thermal limit of the stator winding becoming more of a key constraint. The achievable current density in stator windings is ... En savoir plus

Modelling of a Dual-Probe Heat-Pulse Soil-Moisture Sensor using COMSOL®

R. N. S.[1], R. Aouti[1], G. Ananthasuresh[1]
[1]Indian Institute of Science, Bangalore, India

Measuring soil moisture content plays an important role not only for sustaining dry farming but also for soil mapping. Our work includes developing a soil moisture sensor which is based on the principle of the Dual-Probe Heat-Pulse method to measure soil moisture content. To validate ... En savoir plus
