WebMay 22, 2024 · The 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 acceleration due to Earth’s gravity WebThe Rayleigh scheme for counting modes. We need to evaluate the number of modes which can meet this condition, which amounts to counting all the possible combinations of the integer n values. An approximation can be made by treating the number of combinations as the volume of a three-dimensional grid of the values of n, an "n-space". solo #1 charley wilcoxon
