Fluid jet polishing of optical surfaces
Applied Optics, 1998We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry comprising water and 10% #800 SiC abrasives (21.8 mum) to reduce the surface roughness of a BK7 sample from ...

Wall jet plasma fluid flow problem for hybrid nanofluids with Joule heating
International Journal of Ambient Energy, 2023Hybrid fluids retain excellent energy transportation properties similar to mono-fluids. Like materials they have appliances in obvious fields such as solar collectors and military equipment.

To investigate the effect of atmospheric density and jet-fluid density during supersonic jet-induced cratering on a granular particle bed, large eddy simulation (LES) for the fluid phase coupled with a granular flow model based on kinetic theory is used.

AbstractThe quenching process within the heat treatment of workpieces can be optimized by applying locally adapted quenching conditions. Locally variable heat transfer conditions at the workpiece surface are realizable by impressing and regulation of adjustable flexible flow fields on the basis of arrays for jet flow impingings on surfaces inside the ...

Abstract Constitutive equations for one dimensional incompressible ideal fluid jets are established based on a general theory given by Green and Laws[1]. We discuss the special kinematics of a jet in motion along a fixed curve. It is shown that a circular jet in the atmosphere can move with uniform speed in a straight line and twist in either sense ...
