Investigation of Flow Characteristics inside a Dual Bell Nozzle with and without Film Cooling [PDF]
In this study, we perform a two-dimensional axisymmetric simulation to assess the flow characteristics and understand the film cooling process in a dual bell nozzle. The secondary stream with low temperature is injected at three different axial locations on the nozzle wall, and the simulations are carried out to emphasize the impact of injection ...

Evaluation of the efficiency of cleaning dental plaque on titanium using a cavitating jet
Dental plaque, which adheres to the surfaces of dental implants and remains in the gingival crevices, can cause peri-implantitis, which is similar to periodontal disease; consequently, cleaning the dental plaque from these surfaces is very important.

Breakup characteristics of diesel spray droplets under small valve opening injection
A laser 2-focus velocimeter (L2F) was used for measurements of velocity and size of droplets in diesel fuel sprays. Diesel fuel was injected intermittently into the atmosphere using a 8-hole injector nozzle. The diameter of the nozzle orifice was 0.112mm.

Nozzle contours for minimum particle-lag loss [PDF]
The flow of a gas-particle mixture through a rocket nozzle is analyzed under the approximation that the particle slip velocity is small compared with the average mixture velocity, using one-dimensional gasdynamics, the Stokes drag law, and corresponding ...
