Web9 apr. 2024 · We present spatially and temporally resolved velocity and acceleration measurements of turbulent Rayleigh–Bénard convection (RBC) in the entire fluid sample of square horizontal cross section with length \(L=320\) mm and height \(H=20\) mm, resulting in an aspect ratio of \(\Gamma =H/L=16\).The working fluid was water with a Prandtl … WebIt is a dimensionless number that is a ratio of transfer of heat between the convective (to the fluid) to the conductive (within the fluid). The name is given after a German scientist Wilhelm Nusselt. It is a function of Reynolds and Prandtl numbers. Nusselt Number Formula. The formula of Nusselt number: Nu = h * k / L. In this equation: Nu ...

Prandtl Number Definition, Formula & Calculation
WebPrandtl number for CO 2 and H 2 O in the supercritical critical region Plot the Pr number for CO 2 at 40 °C and H 2 O at 400 °C at pressures from 0.01 to 60 MPa. Solution. The Pr number ( Pr = Cpμ / k) is calculated from Eq. (8.17) and only depends on the properties of the fluid. At a given T and P, the thermodynamic state of the fluid is fixed.

Web7 sep. 2024 · The liquid surface tension coefficient is assumed to be a linear function of temperature. The effects of various dimensionless parameters (including the Marangoni number/Prandtl number, Reynolds number, temperature gradient, Weber number, gas-to-liquid density ratio and velocity ratio) on the instability of the annular liquid jet are discussed. sharyn stone
