Rayleigh regime

WebThe values of the constants C and n depend on the geometry of the surface and the flow regime, which is characterized by the range of the Rayleigh number. The value of n is usually n = 1/4 for laminar flow and n = 1/3 for turbulent flow. The Rayleigh number is defined as: where: g is the acceleration due to Earth’s gravity WebNov 10, 1997 · In a low temperature He gas Rayleigh-B\'enard experiment, Rayleigh numbers from ${10}^{3}$ to more than ${10}^{14}$ are explored.
