Diffusion in Curved Tube [PDF]
Naohisa OgawaDiffusion of particles in confining walls forming tube is discussed. Such a transport phenomena are encountered in biological cell and in porous media. We consider the case that the tube is winding with curvature and torsion, and the thickness of tube is small enough compared to its curvature radius. We will discuss how geomerical quantities appeares in quasi one-dimensional diffusion equation.View original: http://arxiv.org/abs/1109.0590
