Effects of Surface Evaporation and Condensation on the Dynamics of Thin Liquid Films for the Porous Wetted Wall Protection Scheme in IFE Reactors

Thermo Fluid Dynamics and Chamber Aerosol Behavior for Thin Liquid Wall under IFE Cyclic Operation

“…5 for other values of the nondimensional initial film thickness and injection velocity may be found in Ref. 11. Referring to Fig.…”

“…Detailed descriptions of the numerical model and level contour reconstruction method can be found in a companion paper. 11 The results of the calculations have been used to develop nondimensional "generalized charts," which make it possible for system designers to establish "design windows" for successful implementation of the wetted-wall concept. A preliminary experimental investigation aimed at validating the model has also been performed.…”

“…Therefore, these results suggest that a minimum injection velocity will be required to prevent the film thickness from decreasing below a designer-specified minimum value dictated by wall protection requirements. The generalized charts reported in the companion paper 11 can therefore be used to define the operational and design windows necessary for successful operation of the wetted-wall concept. A preliminary experimental investigation aimed at validating the model has been performed.…”
