Generation of thermal and pseudo-thermal plasmas

The Physics of Hybrid Thermal/Non-Thermal Plasmas

Models of the continuum radiation from accreting hot plasmas typically assume that the plasma heating mechanism produces energetic particles distributed in energy either as a Maxwellian (the “thermal” models) or as an extended power law (the “non-thermal” models). The reality, however, is that neither description is probably accurate. In other astrophysical contexts where we have been able to o...

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Heat and Mass Transfer in Thermal Plasmas

The present status of plasma processes involving heat and mass transfer is surveyed, with particular reference to the proceses of vaporization, condensation and chemical reaction. Some of the more important plasma techniques are discussed with emphasis placed on means for maximising the overall thermal efficiency of the mass transfer process, and for controlling the properties of the condensed ...

Particle nucleation and growth in thermal plasmas

Particle nucleation In a thermal plasma reactor occurs as a high-temperature gas undergoes a cooling trajectory. Cooling leads to formation of supersaturated vapours, which causes either homogeneous or ion-induced nucleation. Detailed models have been developed for homogeneous nucleation in a plasma reactor, including discretesectional models and moment-type models. The discrete-sectional model...
