turbulent boundary flow
11laminar flow — noun nonturbulent streamline flow in parallel layers (laminae) • Hypernyms: ↑streamline flow * * * noun : streamline flow in a viscous fluid near a solid boundary contrasted with turbulent flow * * * Hydraul., Mech. the flow of a viscous fluid in …
12controlled separated flow — An airflow that lies midway between a steady streamline (laminar) flow and an unsteady (turbulent) flow. The flow separates at sharp leading edges as a result of the boundary layer effect but does not break down into a turbulent airflow. Instead …
13Plug flow reactor model — The plug flow reactor (PFR) model is used to describe chemical reactions in continuous, flowing systems. The PFR model is used to predict the behaviour of chemical reactors, so that key reactor variables, such as the dimensions of the reactor,… …
14buffet boundary — The speed boundaries within which airflow separates from the wing and the buffet is experienced. The low speed buffet is caused by flow separation as the aircraft approaches the stalling angle of attack. At higher Mach numbers, the high speed… …
15laminar flow — noun Date: 1935 uninterrupted flow in a fluid near a solid boundary in which the direction of flow at every point remains constant compare turbulent flow …
16Turbulence — In fluid dynamics, turbulence or turbulent flow is a fluid regime characterized by chaotic, stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and… …
17Nusselt number — In heat transfer at a boundary (surface) within a fluid, the Nusselt number is the ratio of convective to conductive heat transfer across (normal to) the boundary. Named after Wilhelm Nusselt, it is a dimensionless number. The conductive… …
18Reynolds number — In fluid mechanics and heat transfer, the Reynolds number mathrm{Re} is a dimensionless number that gives a measure of the ratio of inertial forces ({old mathrm V} ho) to viscous forces (mu / L) and, consequently, it quantifies the relative… …
19Adverse pressure gradient — An adverse pressure gradient occurs when the static pressure increases in the direction of the flow. This is important for boundary layers, since increasing the fluid pressure is akin to increasing the potential energy of the fluid, leading to a… …
