چکیده
The cold spray technology mainly accelerates the powder in Laval nozzle by gas, ensuring that has a greater velocity at exit of nozzle, and achieving high-efficiency deposition on substrate, thereby obtaining better performance coating. article uses numerical simulation to study influence length expansion section Dimet acceleration effect Al powder. results show is an essential factor affecting outlet. Through analysis, it can be known pressure inlet range 1.0 MPa, about 210 mm, which ensure It recommended joints between small sections should kept as smooth possible so accelerating gas more uniform stable.

Space Advantage Provided by De - Laval Nozzle and Bell Nozzle over Venturi
Abstract:-The FSAE guidelines state that it is mandatory for each and every car participating in the said event to have a single circular 20mm restrictor in the intake system. All the air flowing to the engine must pass through this restrictor. Conventionally, a Venturi Nozzle is used as a restrictor. In our research, we have proposed two Nozzles: De-Laval Nozzle and Bell Nozzle as an alternati...
متن کاملPulsed Laval nozzle study of the kinetics of OH with unsaturated hydrocarbons at very low temperatures.
The kinetics of reactions of the OH radical with ethene, ethyne (acetylene), propyne (methyl acetylene) and t-butyl-hydroperoxide were studied at temperatures of 69 and 86 K using laser flash-photolysis combined with laser-induced fluorescence spectroscopy. A new pulsed Laval nozzle apparatus is used to provide the low-temperature thermalised environment at a single density of approximately 4x1...
متن کاملA Theoretical Mass Transfer Approach for Prediction of Droplets Growth Inside Supersonic Laval Nozzle
Proper estimation of droplet growth rate plays a crucial role on appropriate prediction of supersonic separators performance for separation of fine droplets from a gas stream. Up to now, all available researches employ empirical or semi-empirical correlations to define the relationship between droplet growth rate (dr/dt) and other operating variables such as temperatures (T and TL), Pressure (P...
متن کاملElectron and Vibrational Kinetics in Supersonic Nozzle Expansion
Vibrational and electron kinetics, as well as electronic excited states and ionization kinetics, have been coupled self consistently solving master and Boltzmann equation at the same time. These kinetics have been inserted in a quasi one-dimensional code for the high enthalpy nozzle expansion. INTRODUCTION The supersonic expansion through a nozzle flow is characterised by strong non-equilibrium...
