Propagation and interference of thermal waves in turbulent thermal convection
Original language description
We report investigation of thermal waves in harmonically modulated turbulent thermal convection in a Rayleigh-Bénard cell. We probe the thermal waves in the working fluid cryogenic helium gas by temperature sensors placed in the cell and embedded in the plates. We observe propagation and interference of two coherent thermal waves and describe their behavior in terms of models that explain the weak attenuation and apparent superposition of thermal waves in the bulk, accounting for the temperature profile of convective turbulent flow via a spatially dependent effective thermal diffusivity.
