nusselt number उदाहरण वाक्य
उदाहरण वाक्य
अधिक: आगे- A larger Nusselt number corresponds to more active convection, with turbulent flow typically in the 100 1000 range.
- On the other hand, correlations for the peripherally averaged Nusselt number for constant wall temperature are very useful.
- The equation yields the surface averaged Nusselt number, which is used to determine the average convective heat transfer coefficient.
- Both correlations utilize the Nusselt number and are only valid when the Reynolds number is greater than 10, 000.
- These correlations are the mass transfer analogies to heat transfer correlations of the Nusselt number in terms of the Reynolds number and Prandtl number.
- A Nusselt number close to one, namely convection and conduction of similar magnitude, is characteristic of " slug flow " or laminar flow.
- This becomes the ratio of conductive thermal resistance to the convective thermal resistance of the fluid, otherwise known as the Nusselt number, Nu.
- In the situation of laminar flow in circular tubes, several dimensionless numbers are used such as Nusselt number, Reynolds number, and Prandtl.
- For this purpose, correlations for the peripherally averaged Nusselt number are, if none, of little use when keeping heat flux conditions constant.
- Using the mass-heat transfer analogy, the Nusselt number is replaced by the Sherwood number, and the Prandtl number is replaced by the Schmidt number.
