When pressurised gas is injected into liquid at high velocity, the bubbles of dispersion are not exactly spherical as normally assumed in theory. High speed photographs of the dispersion show that the bubbles are spheroidal and distinctly prolate in the direction of gas flow. A mechanism of bubble deformation based on the dissipation of the kinetic energy of the injected gas is proposed in this work. The theoretical results are compared with experimental measurements of bubble deformation during high‐velocity injection of air and hydrogen through submerged plate orifices into water.
