| 内容記述 | A nonlinear diffusion equation with a diffusion coefficient depending on number density of diffusing particles affected by gravity is approximately solved in a steady state. Characteristic properties of vapor molecules in a heat pipe are analyzed as diffusion process of Brownian particles. In order to explain the nonlinear shifts from a linear diffusion system in conventional theories, the expectation values and the variance of number density of vapor molecules are calculated by using the theory of stochastic processes. As a result, a diffusion thermal resistance of a heat flow in a heat pipe is estimated by taking an average value of the diffusion coefficient in a nonlinear diffusion system. | |||||||
