Burnout in Forced Convection
Data are presented for burnout in forced coivection nucleate boiling of water at pressures above 500 psia. A dimensionless correlation is devised for. the M.I.T. data which is found to be valid for certain recent data reported by Argonne National Laboratory.
متن کاملPattern formation in spatially forced thermal convection
In this paper, we present experimental results on the interplay between two different symmetry breaking mechanisms in a pattern forming system, namely inclined layer convection (ILC) with a spatially modulated heated plate. By varying the relative strength and relative orientation, we explored in detail the interplay of these symmetry breaking mechanisms. We found a stabilization of spatio-temp...
متن کاملForced convection in metallic honeycomb structures
The heat transfer and pressure drop characteristics of sandwiched metallic honeycomb structures, with one face-sheet heated by constant heat flux and cooled by forced air convection, have been investigated both experimentally and numerically. Six test samples, made of two materials with different thermal conductivities (16.2 W/(mK) for stainless steel and 401 W/(mK) for pure copper), were evalu...
متن کاملForced Convection Subcooled Boiling of Binary Mixtures
A mode based on an additive mechanism of heat transfer is proposed for forced convection subcooled boiling of binary mixtures. The contributing modes of heat transfer are: (i) the heat transferred as latent heat by the rising bubbles, (ii) the heat transferred as the heat contained in the superheated thermal layer that is removed from the surface in the wake of the rising bubbles and (iii) the ...
متن کاملOn the Teaching of the Lumped Model for Unsteady Heat Conduction: Natural Convection Versus Forced Convection
Within the lumped model platform for unsteady heat conduction, the Biot number criterion between a solid body and a surrounding fluid requires that Bi = S V k h s < 0.1. Although not clearly stated, this holds true mostly for forced convection where the mean convective coefficient h is affected by the impressed fluid velocity. Conversely, when heat is exchanged by natural convection...
