An investigation into momentum and temperature fields of a meso-scale slot synthetic jet for a small jet-to-surface spacing
(Begell House Inc., 2014)
Impinging synthetic jets have been identified as a promising technology for cooling miniature structures. Recognizing their thermal performance on the target surface requires a fundamental understanding of the momentum ...
Numerical and experimental analysis of the flow and transition of free synthetic jets
(IOP Publishing, 2019-04)
In this paper, flow characteristics and the transition of synthetic jets are investigated numerically and experimentally. The investigated synthetic jets have a dimensionsless stroke length L-0/d of 146 and 167, an U-0 of ...
An investigation into momentum and temperature fields of a meso-scale synthetic jet
(IEEE, 2014)
Thermal management has become a critical part of advanced micro and nano electronics systems due to high heat transfer rates. More constraints such as compactness, small footprint area, lightweight, high reliability, ...
An experimental and computational investigation of a thin piezofan cooler
(IEEE, 2017)
Recent trends in electronic cooling systems are targeted towards a reduction in size, therefore small form factor/miniature cooling devices are of interest to various applications. Among these devices are piezoelectric ...
Acoustic analysis of an axial fan
(IEEE, 2017)
Axial fans are often used in cooling electronic enclosures where low noise levels are highly demanded. Therefore, methods for predicting the noise emitted by an application including single or multiple fans are desirable ...
Numerical investigation of multiphase flow inside a pressure swirl atomizer at the initial stage of injection
(Begell House Inc., 2018)
Pulse-mode operating atomizers are widely used in industry. This paper presents the fluid flow details and characteristics inside a pulse-mode operating pressure swirl atomizer (PSA). Transient flow simulations are performed ...
Natural convection immersion cooling with enhanced optical performance of light-emitting diode systems
(2015-10-15)
Electronics driven at high currents may experience local hot spots, which may cause thermal degradation or even catastrophic failures. This common problem occurs at light-emitting diode (LED) chips and it is not easily ...
Benchmark study of 2D and 3D VOF simulations of a simplex nozzle using a hybrid RANS-LES approach
(Elsevier, 2022-07-01)
In this study, a simplex nozzle is tested with water for the benchmarking of different flow simulation models. A large scale Plexi-glass transparent nozzle is used to reduce the influence of production tolerances on the ...
Validation and comparison of 2D and 3D numerical simulations of flow in simplex nozzles
(Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2021-08-31)
Numerical simulations of pressure swirl atomizers are computationally expensive due to transient and multiphase flow behavior. In this study, 2D and 3D VOF simulations are performed for a geomerty which has high swirl ...
