The method of matched asymptotic expansions is used to obtain the large-time asymptotic structure of the solution to this problem which exhibits the formation of an expansion wave. “Method of Characteristics” • Basic principle of Methods of Characteristics-- If supersonic flow properties are known at two points in a flow field, -- There is one and only one set of properties compatible* with these at a third point, -- Determined by the intersection of characteristics, or mach waves, from the two original Size: 5MB. This set of equations is known as the set of characteristic equations for (). Once we have found the characteristic curves for (), our plan is to construct a solution of () by forming a surface S as a union of these characteristic curves. Introduction to the method. A ﬁrst order quasilinear equation in 2D is of the form a(x,y,u) u. x + b(x,y,u) u. y = c(x,y,u); () in 3D is of the form a(x,y,z,u) u. x + b(x,y,z,u) u. y + c(x,y,z,u) u. z = d(x,y,z,u). () One can easily generalize this to higher dimensions.

Since ξ=x−at, the solution of the PDE (1a) is simply given by u(x,t)=F(x−at) (5) Indeed, if F has a C1 continuity, it can be easily veriﬁed that u(x,t)=F(x−at)satisﬁes the PDE and the initial condition. The reduction of a PDE to an ODE along its characteristics is called the method of characteristics. Method of characteristics: a special case. I Consider a ﬂrst-order linear homogeneous PDE of the form. a(x;y)ux +b(x;y)uy = 0: In order to solve it, one tries to ﬂnd parametric curves. x = x(s); y = y(s) along which u(x;y) remains Size: 48KB.
