(PDF) GENERAL SELF-SIMILAR SOLUTIONS OF DIFFUSION
WebSuch a solution is therefore called a self-similar solution. We would expect to have a self-similar solution when there is no characteristic length or time scale in the system. This is … Self-similar solutions appear whenever the problem lacks a characteristic length or time scale (for example, the Blasius boundary layer of an infinite plate, but not of a finite-length plate). These include, for example, the Blasius boundary layer or the Sedov–Taylor shell. See more In the study of partial differential equations, particularly in fluid dynamics, a self-similar solution is a form of solution which is similar to itself if the independent and dependent variables are appropriately scaled. Self-similar … See more A simple example is a semi-infinite domain bounded by a rigid wall and filled with viscous fluid. At time $${\displaystyle t=0}$$ the wall is made to move with constant speed See more A powerful tool in physics is the concept of dimensional analysis and scaling laws. By examining the physical effects present in a system, we may estimate their size and hence which, for … See more The normal self-similar solution is also referred to as a self-similar solution of the first kind, since another type of self-similar exists for finite-sized problems, which cannot be derived from dimensional analysis, known as a self-similar solution of the second kind.
