... in a concentric counterflow heat exchanger. Artificial hard water with calcium carbonate hardness of 250 mg/L was used with velocity ranging from 0.1 m/s to 0.5 m/s and zero blowdown. Fouling resistances decreased by 50–72% for the plasma treated cases compared with the values for no-treatment cases, indicating...

... and interaction of such athermal nonequilibrium plasma discharges in conjunction with low Mach number fluid dynamics and heat transfer. The model is self-consistent, coupling the first-principles-based discharge dynamics with the fluid dynamics and heat transfer equations. Under atmospheric pressure...

... for pump beam fluences ranging from 1.5 to 4.6 J / cm 2 provide evidence of plasma expansion above the irradiated target. Contributed by the Heat Transfer Division for publication in the JOURNAL OF HEAT TRANSFER . Manuscript received by the Heat Transfer Division April 22, 2003; revision received...

... thermal conductivity is relatively small. Outside frost sublayer has the highest thermal conductivity when frost deposits on plasma-modified surface with DCA=55 deg. For surfaces with DCA=23 and 88 deg there are the same values for the third and the fourth sublayer. It should be mentioned, that only after...

...Y. P. Wan; V. Prasad; G.-X. Wang; S. Sampath; J. R. Fincke A comprehensive model is developed to study the heating, melting, evaporation, and resolidification of powder particles in plasma flames. The well-established LAVA code for plasma flame simulation is used to predict the plasma gas field...

...S. S. Sripada; P. S. Ayyaswamy; I. M. Cohen A set of self-consistent conservation equations for the charged particle densities and the temperatures in a weakly ionized plasma between two dissimilar electrodes is numerically solved using an orthogonal body-fitted coordinate system. The electron...
