11 Modulo de transferencia de calor e Inglés terms terms
get acquainted with the subject
convection heat transfer coefficient
noun
The rate of heat transfer between a solid surface and a fluid per unit area per unit temperature difference.
es: coeficiente de transferencia de calor por convección
Critical Reynold’s number
noun
Is the ratio of inertial forces to viscous forces and is a convenient parameter to predict whether a flow condition will be laminar or turbulent.
Example: Duct flows and turbulent flows.
es: Número crítico de Reynolds
Friction Coefficient
noun
Is the ratio between the sliding force and the retention force exerted by two surfaces in contact.
es: Coeficiente de fricción
Kinematic viscosity
phrase
It is a measure of the internal resistance of a fluid to flow under gravitational forces.
es: viscosidad cinemática
laminar flow
noun
Movement of a fluid when it is ordered, static and smooth. It moves in parallel sheets without intermingling and each fluid particle follows a trajectory
Example: Water in a garden hose
es: Flujo laminar
Nusselt number
phrase
It is closely related to the Péclet number and both numbers are used to describe the ratio of the thermal energy that is convinced to the fluid with respect to the thermal energy conducted within the fluid.
Example: Cladding surface temperature, cladding is the outer layer of fuel rods, which is located between the reactor coolant and the nuclear fuel.
es: Número de Nusselt
Prandtl number
noun
The ratio of impulse diffusivity to thermal diffusivity.
Example: It is found in the thermal diffusivities of water and air.
es: Número de prandtl
Reynold number
noun
Indicates the relationship between the inertial forces and the viscous forces of a fluid.
Example: In the flow in circular or non-circular conduits, in open channels, and the flow around submerged bodies.
es: Número de Reynold
shear stress
noun
Is the internal or resultant stress of the stresses parallel to the cross section of a mechanical prism.
es: Esfuerzo cortante
Turbulent flow
noun
Is one in which there are fluctuations in the flow all the time and the particles invade the path of the adjacent particles, mixing and moving in a random way.
Example: The flow of water in rivers or the movement of air near the surface of the earth.
es: Flujo turbulento
workbench
noun
a flat table or surface at which carpentry or other mechanical or practical work is done.
