摘要:
Experiments are described concerning the interface instability which arises when an argon‐bromine mixture falls under gravity into air or into helium. Existing theories which include viscosity effects fail to explain the observed amplitude growth rate, but it is shown that approximate inclusion of diffusion effects allows calculation of all features of early perturbation growth accurately to within experimental error.
