Interaction between free-stream turbulence and tip-vortices of wind turbine blades with and without winglets
(IOP Publishing, 2018)
Experimental investigations of the free-stream turbulence impact on the tip-vortices generated in wind turbine blades have been performed. The investigation is done by exposing an efficient laboratory scale wind turbine ...
Active-grid turbulence effect on the topology and the flame location of a lean premixed combustion
(Society of Thermal Engineers of Serbia, 2018)
Lean premixed combustion under the influence of active-grid turbulence was computationally investigated, and the results were compared with experimental data. The experiments were carried out to generate a premixed flame ...
Characterization of turbulence generated by an active grid with individually controllable paddles
(Springer, 2018)
An active grid with individually controllable paddles was constructed to generate strong turbulence (Reλ>200). Measurements of turbulence quantities using the hot-wire technique were conducted in a wind tunnel along the ...
Predicting the performance of pressure-swirl atomizers
(Begell House Inc., 2018)
The purpose of this study is to evaluate the semiempirical correlations that are found in the literature by comparing them with all of the applicable experimental data that are also taken from the literature. Presentation ...
Numerical and experimental analysis of impinging synthetic jets for cooling a point-like heat source
(ASME, 2018-05-01)
High power light emitting diodes (LEDs) being used for low and high beam in automotive lighting need active cooling of their heat sinks by radial or axial fans. But the moving elements of the fan cause abrasion, noise, and ...
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 ...
Numerical investigation of the flame location of turbulent premixed combustion in a diffuser burner exposed to various turbulence intensities and turbulence length scales
(Turkish Society of Thermal Science and Technology (TIBTD), 2018)
This study aims to investigate the response of the flame location of a turbulent premixed flame that has been exposed to various turbulence intensities and turbulence length scales. A diffuser-type burner is used to reveal ...
Flow visualization and LES simulations inside a chevron type plate heat exchanger
(Begell House Inc., 2018)
An up-scaled model of a single channel of CPHE was used under dynamically similar conditions for the experiments. In experiments, pressure drop measurements and flow visualizations were conducted with aluminum flitter and ...
