Manipulation of Heat Dissipation from Sides of Electrolytic Cells
… risk of causing significant disturbance to the thermal balance of the electrolytic cells which will cause early failure. This can cause production losses and generate considerable waste material that is toxic and expensive to dispose. There are many approaches adopted in Aluminium industry for …

Kinematics and energetics of the mesoscale mid-ocean circulation : MODE
… contributes significantly to the low frequency thermal balance. The observed very low frequency anisotropic flow is consistent with the nonlinear eddy spindown models, dominated by cascades of vorticity and energy. At high frequencies, the spectral similarity is consistent with advected …

Assessment of mesoscale eddy parameterizations for coarse resolution ocean models
… provide a significant contribution to the thermal balance in limited areas of the domain associated with the upper 1000M of the boundary regions. Specifically designed diagnostic tests of the schemes show that the horizontal and vertical components of the parameterized flux are not …

Pneumatic Tire Performance on Ice
… the pressure distribution in the contact patch, thermal properties of the tread compound and of the ice surface. The contact patch is then classified into wet and dry regions based on the ice surface temperature and temperature rise simulations. The principle of thermal balance is then applied to …

Examining the roles of core and local temperature on forearm skin blood flow
The interaction between local and reflexive control of skin blood flow (SkBF) is unclear. This thesis isolated the roles of rectal (Tre) and local (Tloc) temperature on forearm SkBF regulation at normal and elevated body temperatures, and to investigate the interaction between local and reflexive …

Enhanced Laminar Convective Heat Transfer using Microstructured Superhydrophobic Surfaces
… resulting velocity profile was input into the thermal balance equation which was numerically solved. The model assumed hydrodynamic slip but not thermal slip nor a temperature jump at the boundary, and as a result, it predicted a net increase in heat transfer performance. For the experimental …

Ventilerad luftspalt i yttervägg : luftomsättningar och konvektiv fukttransport
Allvarliga fuktproblem i ytterväggar med regelstomme av trä och fasadskikt av puts på isolering har under senare delen av 2000-talet konstaterats i Sverige. Ett alternativ byggsätt för den putsade fasaden är att putsa mot ett skivunderlag som sitter monterat mot läkt så att en luftspalt bildas. Om …
