The wall shear stress produced by the normal impingement of a jet on a flat surface [PDF]
, 2000 A method for the theoretical determination of the wall shear stress under impinging jets of various congurations is presented. Axisymmetric and two-dimensional incompressible jets of a wide range of Reynolds numbers and jet heights are considered ...

Algal lipid extraction using confined impinging jet mixers
Chemical Engineering Science: X, 2019 We show that confined impinging jet mixers (CIJMs) improve lipid extraction from microalgae. CIJMs turbulently mix organic solvent into algae suspensions.

DNS analysis of multiple impinging jets
Journal of Fluid Science and Technology, 2014 In order to elucidate the heat and flow characteristics of multiple impinging jet (MIJ), we conduct the DNS (direct numerical simulation) of four round impinging jet arranged at an inflow of flow field.

Unsteady behavior of a sweeping impinging jet: Time-resolved particle image velocimetry measurements
Experimental Thermal and Fluid Science, 2018 The unsteady behavior of a sweeping impinging jet is measured experimentally using time-resolved particle image velocimetry. For the configuration with a jet-to-wall spacing ratio L / d h = 8, an approximately linear increase in the sweeping frequency ...
