Abstract: To improve the resolution accuracy and get deep insight into the flow structures in squealer tip gap, the very large Eddy simulation (VLES) method was implemented into the commercial computational fluid dynamics (CFD) ...

Abstract: The wear behaviors of the rectangular labyrinth seal fin against high-speed rotor were experimentally investigated on the incursion test rig. The material losses, worn geometries, frictional temperature distributions, and ...

Abstract: Heat transfer and aerodynamic performance in worn squealer tip gap of a high-pressure gas turbine stage were numerically investigated. Effects of the starting location of wear and wear depth on tip heat transfer coefficient ...

Abstract: The process of charging and discharging of lithium-ion batteries results in the periodic intercalation and ejection of lithium ions in the anode material. High-capacity anode materials that are of significant interest for ...

Abstract: A numerical method using the multiple frequencies elliptical whirling orbit model and transient Reynoldsaveraged Navier–Stokes (RANS) solution was proposed for prediction of the frequency dependent rotordynamic coefficients ...

Abstract: Effects of non-axisymmetric endwall profiling on total pressure loss, heat transfer, and film cooling effectiveness of a transonic rotor blade were numerically investigated. The numerical methods, including the turbulence ...

Abstract: The wear characteristics of the trapezoidal fin against high-speed rotor were experimentally investigated at different final incursion depths, incursion rates, and sliding velocities. To characterize the geometrical effect, ...

Abstract: Cavity separation baffles can decrease the circumferential swirl intensity of labyrinth seals and increase the seals' rotordynamic characteristics. Compared with conventional baffles, the bristle packs of brush seal baffles ...

Abstract: This study reports an experimental work on friction contact between the chamfered labyrinth fin and high speed rotor at different incursion rates, final incursion depths, and sliding velocities. The small (original design ...

Abstract: The rotordynamic characteristic of the holepattern seals with two different holediameters was investigated using the unsteady Reynoldsaveraged Navier–Stokes (URANS) equations solutions and bulk flow methods. The mesh ...
