One of the most daunting challenges in the Cold Gas Dynamic Spray (CGDS) process is the calculation and design of the nozzles that are used to accel- erate the gas and the powder particles at supersonic speeds and so promote the deposition process. Past research into this area resulted in a wealth of knowledge but
Summary.--This paper presents a method of design of a supersonic nozzle which incorporates recent developments in compressible flow theory. Continuous curvature of the contour is ensured by defining a continuous gradient of Prandtl-Meyer angle along the nozzle axis. The flow in the throat was calculated from results
7 Jul 2017 perfect gas is accelerated from the Mach number M1 to the Mach number M2, where M2>M1?1. The inlet flow and. the exit flow are uniform. The flow is steady, isentropic, isoenthalpic and irrotational. The solution is numerical. Used the characteristic equation and the compatibility conditions on them: ,0.
Full-text (PDF) | In this paper, a method based on the theory of characteristics is presented for two-dimensional, supersonic nozzle design. Minimum length of the supersonic nozzle has been calculated for the optimum Mach number at the nozzle exit with uniform flow at the diverging section of the
Critical to the design of efficient air vehicle systems is the design of the gas turbine exhaust nozzle. Aircraft exhaust nozzles serve two primary functions. First, they must control the engine backpressure to provide the correct, and optimum, engine performance, which is accomplished through jet area variations. Second,.
combine several of these design elements. Fan nozzles that produce very large droplets at all pressure ranges include Spraying Systems Co.'s Turbo TeeJet Induc- tion, Turbo FloodJet, and TurfJet. The standard flat-fan nozzle normally operates between 30 pounds per square inch (psi) and 60 psi, with an ideal range of
shock waves form, and nozzles are relatively short), so that the isentropic model all along the nozzle is good enough for preliminary design. The nozzle is said to begin where the chamber diameter begins to decrease (by the way, we assume the nozzle is axisymmetric, i.e. with circular cross-sections, in spite that rectangular
than a few millimeters then a fully viscous, non-isentropic treatment of the flow is required. Accurate nozzle design, regardless of size, virtually always requires that the boundary layer on the wall of the plenum and nozzle is taken into account. If the ambient pressure equals the reservoir pressure there is, of course, no flow.
