Numerical study on the effect of gravity angle on airborne spray cooling with different coolants

Energy Storage and Saving
In spray cooling systems designed for airborne equipment or confined packaging conditions, the angle between the spray direction and gravity, known as the gravity angle, significantly affects cooling performance.

Modification of the CAB Model for Air-Assist Atomization of Food Sprays [PDF]

, 2014
The Cascade Atomization and Drop Breakup (CAB) model has been originally developed for pressure atomizers. In this study, the CAB model is modified to accommodate the atomization of low-pressure, air-assist atomizers.

Heavy rain effects on airplane performance [PDF]

The objective is to determine if the aerodynamic characteristics of an airplane are altered while flying in the rain. Wind-tunnel tests conducted at the NASA Langley Research Center (LaRC) have shown losses in maximum lift, reduction in stall angle, and ...

Justification of range limits of root spray angle of an adaptive spraying device

Tractors and Agricultural Machinery
BACKGROUND: Oscillations of the sprayer field boom in the transverse-vertical plane causes a decrease in the quality of the technological operation. This is especially true in relation to the operation of small-sized single-support barrow-type sprayers. One of the possible solutions to compensate the effect of transverse oscillations of the boom on the

Initial experimentation on the nonvented fill of a 0.14m3 (5 ft. 3) dewar with nitrogen and hydrogen [PDF]

A series of nonvented fills were performed on a 0.14 cu m (5 cu ft) stainless steel dewar. Fills were conducted with a 120 deg cone angle spray nozzle over a range of inflow and initial wall temperatures with both liquid nitrogen and liquid hydrogen ...

Atomization of water jets and sheets in axial and swirling airflows [PDF]

Axial and swirling airflows were used to break up water jets and sheets into sprays of droplets to determine the overall effects of orifice diameter, weight flow of air, and the use of an air swirler on fineness of atomization as characterized by mean ...
