thermal convection การใช้

• Inserting these substitutions produces a Rayleigh number that can be used to predict thermal convection.
• Upper ocean turbulence can result from many sources, including thermal convection, wind, waves, and Langmuir circulation.
• Unlike heat transmitted by thermal conduction or thermal convection, thermal radiation can propagate through a vacuum.
• The essential feature of the gel required is that thermal convection in the tube be prevented altogether.
• Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
• :No . It gets continually mixed up by thermal convection, so radioactive isotopes never get nearly that concentrated.
• :To model this realistically is not simple; because hotter air is lighter you also get circulation and thermal convection.
• In the United States, it was not until the late 1960s that thermal convection replaced the shrinking Earth theories.
• Of course, this does not apply if oxygen is supplied to the fire by some process other than thermal convection.
• The equation is named after the authors of the paper, where it was derived from the equations for thermal convection.
• Mascart's graduate student Henri B閚ard carried out groundbreaking experiments in thermal convection, as part of his dissertation research, in Mascart's laboratory.
• For Mother's Day, Smyers gave his wife a double thermal convection oven with as many buttons to push as a VCR.
• Schlieren image reveals thermal convection from a human hand ( in silhouette form ) to the surrounding still exchange . ]]
• Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.
• :: Thermal convection currents will slow down the net movement of heavy elements towards the core consideably, and may even prevent it.
• For thermal convection due to heating from below, as described in the boiling pot above, the equation is modified for thermal expansion and thermal diffusivity.
• He is well known for his contributions to the field of fluid dynamics in the areas of wall turbulence, thermal convection, coherent structures in turbulence and laser instrumentation.
• Because thermal convection alone appears to be improbable, any buoyant convection motions will have to be driven by variations in composition or abundance of liquid in its interior.
• Thermal convection also occasionally brings up hot magma to near the surface, causing volcanism of various degrees . talk ) 00 : 41, 10 April 2010 ( UTC)
• Vertical furnaces solve this problem by having wafer sitting horizontally, and then having the gas flow in the furnace flowing from top to bottom, significantly damping any thermal convections.
