Particulate Laden Flows in Turbomachinery and Consequences

Particle-laden turbulent flows are commonplace in many applications such as industrial processes, power generation and propulsion, among others. The ingestion of particles may cause erosion and fouling of the compressors blades and deposition on the turbine blades, etc... Also, liquid droplets may induce similar effects for turbomachinery blades. Therefore, an accurate description of particle transport and removal in turbulent flow fields is of great importance. This Research Topic solicits brief, forward-looking contributions that describe the state of the art concerning particulate flows in turbomachinery, erosion, fouling and deposition.

The main concern is to highlight recent developments and major advances made by many researchers in the simulation and experimental methods. Authors are encouraged to identify the main technological concerns and address those challenges by proposing solutions for the benefit of constructors and users of such equipment.

The goal of this Research Topic is to present an inventory of existing approaches: experimental and numerical tools and their advances, as well as major challenges of modelling particulate flows by focusing on applications of turbomachines in the process industry, production electricity, aerospace and hydropower. This Research This subject will inspire and guide researchers working in the field of gas and liquid turbomachines, but limited to the following aspects:

– Particle dynamics and tracking methods
– Particle and flow interaction, turbulence effect
– Assessments of Erosion and geometry degradation
– Assessments of Performance deterioration
– Erosion by liquid droplets

Keywords: Turbomachinery, Particle-laden flows, Particle tracking, Impacts, Erosion

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
