Webb11 apr. 2024 · The fluids are enclosed in an annular region bounded by two rigid concentric cylinders. The non-dimensional dispersion relation depends on the capillary number, Weber number, power-law index, heat transfer coefficient, viscosity ratio of fluids, etc. The transfer of heat and mass has a significant impact on the stability of the interface. WebbTheory: Heat transfer theory seeks to predict the energy transfer that takes place between material bodies as a result of temperature difference. This energy transfer is defined as heat. The three modes by which heat can be transferred from one place to another are conduction, convection and radiation.
