Numerical and experimental investigations on thermal interaction between thermal plasma and solid polymer powders using induction thermal plasma technique

Thermal Plasma Synthesis of Nano-sized Powders

Thermal plasmas, normally generated by DC (direct current) arc or inductively coupled RF (Radio Frequency) discharge, can be described as a high enthalpy flame with extremely high temperature fields (1,000~20,000 K) and a wide range of velocity fields from several m/s [1-5] to supersonic values [6-7]. Since the resultant huge enthalpy can be realized for various kinds of plasma forming gases an...

Experimental and Numerical Investigations on Al2O3–Tricosane Based Heat Pipe Thermal Energy Storage

The enhancement of operating life cycle of electronic devices necessitates the development of efficient cooling techniques. Therefore, in the present work the effects of employment of Phase Change Material, in the adiabatic section of heat pipe for electronic cooling applications were experimentally and numerically investigated. Tricosane (100 ml) is chosen as PCM in this study, where Al2O3 nan...

Optimizing Compliance and Thermal Conductivity of Plasma Sprayed Thermal Barrier Coatings via Controlled Powders and Processing Strategies

Thermal Destruction of Waste Using Plasma

Thermal technologies for the treatment of waste are once again attracting interest, particularly in Europe and North Amerca, as landfill space becomes scarcer and landfill regulations become more stringent. Plasma technologies can be used to destroy waste at high temperatures, using electricity to convert waste into a fuel gas and an inert rock. The Plasma Arc Waste Destruction System’s (PAWDS)...

Numerical and Experimental Investigation of Thermal Debinding

Powder injection molding (PIM) is an important netshape manufacturing process and has received much attention. One of the most critical steps in PIM process is debinding. It consumes a major part of the processing time. Failure of the powder compact often results if the process is accelerated. Thermal debinding is a common methodology for the final removal of residual polymer from a PIM compact...
