A plane pi passes through the point (1,1,1) and is parallel to the vectors vecb=(1,0-1) and vecc=(-1,1,0). If pi meets the axes in A,B, and C, find the volume
4 A particle P moves on a straight line, starting from rest at a point O of the line. The time after P starts to move is ts, and the particle moves along the line with constant accelerationms2 until it passes through a point A at time t = 8. After passing through A the velocity...

Core/shell microdroplets formation with uniform size is investigated numerically in the co-flow microchannel. The interface and volume fraction contour between three immiscible fluids are captured using a ternary phase-field model. Previous research has
