“…Albert et al [15,16] simulated particle deposition at the turbine vane leading edge and on the pressure surface in a low-speed wind tunnel facility by matching the Stokes numbers and thermal scaling parameter (TSP). Zhang et al [17,18] carried out deposition tests at different mainstream temperatures and velocities with wax particles and found deposition mass increased initially and then decreased with the mainstream temperature or velocity. Zhang et al [19] also investigated the effect of the angle of attack and particle concentration on the wax deposition behavior.…”

Particle deposition tests were conducted in a turbine deposition facility with an internally staged single-tube combustor to investigate the individual effect of the gas temperature and angle of attack. Sand particles were seeded to the combustor and deposited on a turbine blade with film-cooling holes at temperatures representative of modern engines. Fuel-air ratios were varied from 0.022 to 0.037 to achieve a gas temperature between 1272 and 1668 K. Results show that capture efficiency increased with increasing gas temperature. A dramatic increase in capture efficiency was noted when gas temperature exceeded the threshold. The deposition formed mostly downstream of the film-cooling holes on the pressure surface, while it concentrated on the suction surface at the trailing edge. Deposition tests at angles of attack between 10° and 40° presented changes in both deposition mass and distribution. The capture efficiency increased with the increase in the angle of attack, and simultaneously the growth rate slowed down. On the blade pressure surface, sand deposition was distributed mainly downstream of the film-cooling holes near the trailing edge in the case of the small angle of attack, while it concentrated on the region around the film-cooling holes near the leading edge, resulting in the partial blockage of holes, in the case of the large angle of attack.

“…Peng Li et al [17] performed a study on dissociation processes of gas hydrate-bearing sediment particles in water flow condition. Fei Zhang et al [18] performed a study on the effect of mainstream velocity and mainstream temperature on the behavior of deposition on a flat plate surface experimentally. Kiao Inthavong, Yen- Cheng Chang, and C Tao et al [19][20][21] studied the deposition movement of particulate matter in different pipelines.…”

Study on the Movement and Deposition of Particles in Supercritical Water Natural Circulation Based on Grey Correlation Theory

et al. 2019

The movement and deposition of particles that occur during their natural circulation in supercritical water exercise an important impact on the safe and stable operation of a supercritical water reactor (SCWR). When supercritical water flows in pipelines, a large number of corrosive particles may be generated due to pipeline corrosion or the purity of the fluid itself. The presence of particulate matter affects the heat transfer efficiency of the pipeline, increasing flow resistance and easily promoting heat transfer deterioration. ANSYS-CFX numerical analysis software was used to simulate the natural circulation loop of supercritical water, and micron particles were added in the initial flow field. The effects of heating power, particle concentration and particle diameter on particle deposition were obtained. Through this analysis, it can be concluded that the heating of the pipeline has a certain inhibitory effect on the deposition of particles. The rise in both initial particle concentration and particle diameter serve to reinforce the deposition of particles in the heating section. Depending on the degree of influence, the contributory parameters to particle deposition include particle diameter, particle concentration and heating power in turn.

“…The fourth theme of research that emerged can be referred to as "Flow with micro-and nano-scale features". This includes the following papers: There are two papers dealing with microbubbles present in the flow [14,15], a nanofluids application [16], ferromagnetic fluid behaviour [17] and a particle deposition problem [18].…”
