 In , a study was made of the generation and propagation of a wave from a bow front in the form of a circular arc. Effect of non-equilibrium condensation of moist air on unsteady behaviour of shock waves around a circular arc blade In the present study, the effect of non-equilibrium condensation of moist air on the self-excited shock wave oscillation on a circular arc blade was investigated numerically. We consider a potential energy trough centered along a circular arc of radiusR. We consider a problem for the Laplace equation in a circular sector wherein heat exchange takes place on the sides of the sector in accordance with Newton's law and a temperature distribution is specified on the circular arc. 更多 circular arcs
 The trajectory consists of line segments and circular arcs. "Extremal" nozzles designed by variational methods in the absence/presence of internal shocks (I), so-called "truncated" nozzles with a uniform characteristic (II), and nozzles designed by the method of conjugate circular arcs (III) are considered. The thrust characteristics of nozzles designed by the method of conjugate circular arcs for both inviscid and viscous flow are inferior to those of extremal nozzles by 0.7-1%. The end field is formed with the help of wire sections in the form of straight lines and circular arcs, which permits an accurate control of geometrical dimensions. The use of the method is exemplified by calculating the characteristics of a gas-drop flow in curved channels in which the generatrices of the lateral surface consist of circular arcs. 更多 In tab. 1 are given the deflection formulas of circular beams (with one end fixed) under concentrated load.
