Numeric simulation of liquid and gas flows on a basis of alternating-triangular differential circuits

The investigation is concerned with liquid and gas flows, associated problems of heat exchange, stationary problems of "associated" aeroelasticity. The aim to be attained is development of a new class of differential circuits and creation of complexes of multipurpose programs for calculation of liquid and gas flows. A new trend of numeric simulation of the problems of liquid and gas mechanics has been elaborated, the analytical solutions of Aler and Navier-Stokes equations have been used as interprolants, the quasimonotonous differential circuits have been constructed, program complexes have been created. The practical results include the development of program aids of simulation of viscous and nonviscous gas flows in the channels of a complex geometrical shape, solution of associated tasks of cooling or heating of bodies in a liquid flow, simulation of the flow interaction with deforming shells.
