Grid influence issues in the methodology of numerical modelling of non-stationary combustion processes
Published 2025-03-01“…The use of computational fluid dynamics (CFD) tools for calculating combustion flows in the combustion chamber of a gas turbine engine is currently an integral part of the design process, since a numerical study, in contrast to a full-scale experiment, requires significantly fewer material resources providing the ability to model expensive and unsafe cases of aircraft flight operation that are difficult to implement at the stage of bench tests, such as: crossing a jet distrail or a shock wave front (e.g., when an ammunition detonates) in front of the air intake of an air-jet engine, critical crosswind during takeoff leading to flow separation on the air intake cowl, vertical gusts and atmospheric turbulence, flight at high angles of attack, aircraft evolution (slip, etc.). …”

River Floods Under Wetter Antecedent Conditions Deliver Coarser Sediment to the Coast
Published 2025-04-01“…In years with multiple 2‐ to 10‐year floods, fluvial sediment coarsened significantly as the wet season progressed, with late‐season floods delivering dominantly sand‐sized material to the coast. Greater and coarser sediment supply under wetter antecedent conditions affected nearshore geomorphic evolution for 4–5 years. …”
