Using transient and stationary mathematical heat transfer models including heat conduction, radiation, and radio frequency (RF) induction heating, we numerically investigate the time evolution of temperature gradients in axisymmetric growth apparatus during the sublimation growth of silicon carbide (SiC) bulk single crystals by physical vapor transport (PVT) (modified Lely method). Temperature ...

Superparamagnetic magnetite nanoparticles (MNPs), Fe3O4, were synthesized via the modified coprecipitation method. The morphology of these MNPs is polyhedral. The particle size of MNPs ranged from 20 to 100 nm. For combined hyperthermia and thermoresponsive drug delivery applications, the heating element, MNPs, in the core of drug carriers should increase the temperature of the target up to 43 ...

Trinidad has tar sand resources of about 2 billion barrels of oil on land in the Parrylands/Guapo and Brighton areas. With an oil price of over USD 25 per barrel, the commercial extraction of oil from Trinidad tar sands is viable, but it requires a careful study. The relatively small extent of this tar sand (about 10,000 acres and with depths varying from surface to less than 500 feet) and with...

This paper deals with the issues relevant for precise finite element method (FEM) modeling of thin molybdenum plates’ induction heating. The proposed methodology describes step-by-step Multiphysics (electro-thermal) design approach, verified by experimental measurements. Initially, it was observed that relative error between model and set-up is within 1.2% up to 2.5% depending on location measu...

-This paper presents a review of different types of Induction cooker design which can be used for domestic heating and industrial heating applications. The designs focus on optimized power regulation strategy.

The induction heating process at a domestic level is getting attention nowadays as this power converting topology ensures clean, reliable, flexible, and fast operation. low input frequency converted to required regulated high output with indirect direct approaches. circuit control complexity conversion losses associated approaches lower their uses for systems. ac-ac approach one of the viable s...
