{"Image DocumentName": "Chapter 6 : Introduction to Conduction \u2013 Flow & Thermal Considerations", "Image ImageDescription": "Thermal Boundary Layers \u2013 Physical meaning/features. A consequence of heat transfer between the surface and fluid. A region of the flow characterised by temperature gradients and heat fluxes. A region between the surface and the free stream whose thickness, \uf064t increases in the flow direction. why does \uf064 increase in the flow direction ? - the heat transfer effects penetrate further into the free stream along the plate and \uf064 increases. Manifested by a surface heat fluxes, q s and a convection heat transfer coefficient, h. If (Ts \u2013 T\uf0a5) is constant, how do q s and h vary in the flow directions ? - The temperature gradient at the wall, h and q s decrease with increasing x.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
