Parametric Effects on Internal Aerodynamics of Lobed Mixer

The internal flow characteristics inside lobed mixer-ejector with curved mixing duct and the parametric effects on the lobed mixer-ejector performance are investigated numerically and validated by experimental test. The curved mixing duct affects the development of the streamwise vortices induced by the lobed mixer.

Experimental Measurement of the Vortex Development

An experiment was set up to investigate the mixing processes downstream of a mixer. Air flow was independently supplied to each side of the forced mixer by separate centrifugal blowers. Pressures were measured at the entrance to the lobes with a pitot-static probe to document the characteristics of the approaching boundary layer.

QTA Gulfstream Stage 3 Hush Kits – Quiet Technologies Aerospace

The QTA Hush Kit retains the original Gulfstream TM acoustically treated tailpipe, the original 5 lobe mixer nozzle is removed and replaced with a 12 lobe “fluted” mixer nozzle. The 12 lobe nozzle works with the ejector in promoting the mixing of the ambient air stream with the jet exhaust.

Computational Fluid Dynamics Analysis of Jets with Internal

The results for one confluent mixer and three forced mixer geometries are presented in this paper. The confluent mixer geometry, shown in Figure 1, is an axisymmetric splitter plate which separates the bypass and core flows. All three forced mixers, which are essentially convoluted splitter plates, have 12 lobes and are of similar designs.

Performance Simulation of an ideal mixer-ejector turbofan

The mixer-ejector engine consists of a low-bypass ratio mixed flow turbofan coupled to an exhaust mixer ejector configuration (ejector doors and forced mixer) followed by a condi-nozzle (Fig. 1). NLR’s Flight Physics Department (AVFP, Laban) did exploratory CFD design calculations with an Euler code to capture the main flow physics of the ...

Visualization of Flows behind the Lobed Forced Mixers Using

Flow visualization studies have been conducted using the smoke-wire technique to examine the flows behind lobed forced mixers of different trailing edge configurations (namely a square wave, semi-circular wave and a triangular wave) at a velocity ratio 1:1 across the lobe.

Stereoscopic PIV measurement of a lobed jet mixing flow

Abstract. In a continuing effort to study the mixing enhancement by large scale streamwise vortices generated by a lobed nozzle, a high-resolution stereoscopic PIV system was used in the present study to conduct three-dimensional measurements of air jet flows exhausted from a lobed nozzle and a conventional circular nozzle.

Numerical Simulation of Lobed Exhaust Ejector

Exhaust ejectors are good ventilations and cooling equipments. By the method of numerical simulation, researches on cylindrical exhaust ejector, lobed exhaust ejector and lobed exhaust ejector with twisted blades are conducted in this paper to study the effects of different ejector structures on flow field uniformity.

Manual for the Design of Pipe Systems and Pumps

due to the earth’s gravitational force is today unthinkable. Liquids are forced through pipes, valves, heat exchangers, filters and other components, and all of them cause an increased resistance of flow and thus pressure drops. Pumps are therefore installed in different sections of a plant. The choice of the right pump at
