Reduced model for particle laden flow
The flow of thin liquid films on solid surfaces is a significant phenomenon in nature and in industrial processes where uniformity and completeness of wetting are paramount in importance. It is well known that when a clear viscous fluid flows down an inclined surface under gravity, after some time, …

Simulation of filtration for suspension transport in porous media
… a novel method for analyzing the filtration of particles transported through a granular porous medium. The proposed analysis considers the deposition of particles through discrete simulations of particle-laden flow in a cylindrical model pore. The pore model assumes that particles collect, mound …

Investigation of Particle Trajectories for Wall Bounded Turbulent Two-Phase Flows
The analysis of turbulent flows provides a unique scientific challenge whose solution remains central to unraveling the fundamental nature of all fluid dynamics. Measuring and predicting turbulent flows becomes even more difficult when considering a two-phase flow, which is a commonly encountered …

Evaluation of a Particle Sampling Probe to Measure Mass Concentration in Particle-Laden Flows
Particle ingestion is a prevalent issue for jet engines. During operation, sand and ash particles enter the engine and can cause serious problems, including erosion and buildup of Calcia-Magnesia-Alumina-Silicate (CMAS) deposits. Analyzing the particle mass concentration of the airflow can help …

An image processing technique for erosion analysis on compressor blade geometry
Particle ingestion into aircraft engines is a major concern due to its physical- and performance-related implications; largely due to compressor blade material erosion. Current methods for monitoring this erosion (such as visual tools) lack adequate reliability and consistency, while only providing …

Development of Diagnostic Tools for Use in a Gas Turbine Engine Undergoing Solid Particulate Ingestion
… operations as significant amounts of groundlevel particles can be entrained in the surrounding air and subsequently ingested into the engine. Prolonged exposure to particle ingestion events leads to premature engine wear and, in extreme cases, rapid engine failure. Expanding our current …
