The valveless micropump based on dual synthetic jets is a potential fluid pumping device that has the ability to transport continuously. In order improve performance of this device, novel continuous with Tesla structure was proposed by combining double symmetrical nozzle and actuator. mechanism its flow field characteristics were analyzed, combined numerical simulation PIV experiment. compared ...

Temperature and pressure as two important working conditions of the air ejector are very to its performance. Taking installed in a power plant an example, using ANSYS-FLUENT software, three-dimensional simulation operation under different temperature is carried out, relations between pressure, temperature, inlet gas flow rate ejection coefficient given. The results show that have some influence...

A straightforward procedure has been developed to quickly determine an inviscid design of a hypersonic wind tunnel nozzle when the test gas is both calorically and thermally imperfect. This real gas procedure divides the nozzle into four distinct parts: subsonic, throat to conical, conical, and turning flow regions. The design process is greatly simplified by treating the imperfect gas effects ...

Modern aircraft and missiles are gradually integrating thrust vector control systems to enhance their military capabilities. Bypass Dual-Throat Nozzle (BDTN) is a new fluidic vectoring technique capable of achieving superior performance with large angles low loss. In this study, we analyzed the flow characteristics parameters BDTN by varying bypass angle, nozzle convergence width. The governing...

The mass of individual droplets ejected from a thermal inkjet printhead increases with increasing local temperature near the ejector nozzles. amount ink deposited on page and so printed image density depends droplet mass. Thus, nonuniformity results in variations that can be unacceptable to end users output. Such arise combination fluid flow heat transfer both solid components printhead. Conjug...

We establish the existence and stability of multidimensional transonic flows with transonic shocks through an infinite nozzle of arbitrary cross-sections, including a slowly varying de Lavel nozzle. The transonic flow is governed by the inviscid steady potential flow equation with supersonic upstream flow at the entrance, uniform subsonic downstream flow at the infinite exit, and the slip bound...
