Engineering Applications of Computational Fluid Mechanics, 2021 In this study, the unique reverse-flow around the inlet nozzle of a squirrel-cage fan was numerically studied by computational fluid dynamics (CFD), and a non-axisymmetric D-type inlet nozzle was proposed to inhibit it. It is shown that serious back flow

Spheres, tears, and spears: Regulating the perimeter and circularity of millimeter-sized alginate hydrogel beads. [PDF]
AIChE JAbstract Generating hydrogel beads pertains to many engineering applications. We examined two alginate‐based fluids at three concentrations of alginate, cAG. We used the “Map of Misery” to determine which material property (viscosity, elasticity, and inertia) drives droplet formation. Next, we measured the perimeter and circularity of hydrogel beads as

Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability. [PDF]
Adv Sci (Weinh)A novel dancing electrospray phenomenon is reported characterized by high‐frequency, robust, and multi‐directional alternating ejection modes. This phenomenon arises from the electrohydrodynamic (EHD) tip streaming at the crests of Faraday waves excited on the liquid meniscus, and it offers significant advantages in high‐throughput and multi‐path ...

Wide-Flow Aerosol Jet Printing Enables High-Throughput, Ultra-Low Aspect Ratio Patterning. [PDF]
Adv Sci (Weinh)Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

Design and performance evaluation of a high temperature axisymmetric plug nozzle [PDF]
INCAS Bulletin, 2023 In this study, a method for designing supersonic nozzles with axisymmetric plugs at high temperature has been proposed. The approach is based on the theory of Prandtl-Mayer expansion at high temperatures using the method of characteristics.

Numerical Simulation of Low Reynolds Number Particle-Laden Gas Jet by Vortex Method
Journal of Fluid Science and Technology, 2009 An air jet, which remains laminar and axisymmetric in the single-phase flow condition, is simulated numerically in the particle-laden condition. The vortex method for particle-laden gas jet proposed by the authors is employed for the simulation.

The thermochemical non-equilibrium scale effects of the high enthalpy nozzle
Advances in Aerodynamics, 2020 The high enthalpy nozzle converts the high enthalpy stagnation gas into the hypervelocity free flow. The flow region of the high enthalpy nozzle consists of three parts: an equilibrium region upstream of the throat, a non-equilibrium region near the ...
