A numerical study of open atmospheric balloon dynamics

Mostrar todas las versiones(3)

The dynamics of open balloons in an atmosphere may be studied with a body-fluid coupled model. A numerical approach is required to solve the corresponding equation set. Solutions under different conditions are obtained here for the vertical and one horizontal direction. Relevant dynamical features d...
