The Tricomi Problemicomi problem is a typical example of numerous problems arising in the study of plane transonic flows of compressible gas, e.g., of flows in the Laval nozzle or flows around contours. The Tricomi equation has the form . It is an equation of mixed type, since it is elliptic for . > 0 and hyperbolic for . < 0.

Problems of Internal Flows of Viscous Incompressible FluidsNonstationary flows of viscous incompressible fluids can be modeled as boundary-value problems for systems of differential Navier-Stokes equations. In the case of three-dimensional problems, the desired functions are velocity and pressure. In the case of plane flows, one can also use the stream function and vorticity as desired functions.
