... (1) For the combined waves and currents under test, the relative directions of flow do not influence the interaction near the bed, whereas in the upper layer mean velocit[r] ... See full document

... The morphological evolution of a schematic beach was simu- lated to assess model results, considering the beach response for different designs of detached breakwaters and groynes. Constant wave conditions were defined ... See full document

... and vertical boundary layers of depth order R − 1/3 near the upper surface, where R 1 is the Darcy–Rayleigh number based on the cavity depth and the temperature difference along the upper ...a ... See full document

... low‐frequency waves generated in the ionosphere during heating experiments with modulated HF waves (1–10 MHz) originate from multiple physical mecha­ nisms that operate at different altitudes and ...HF ... See full document

... Disturbances propagation processes are investigated in two-dimensional boundary layers for the case of strong viscous-inviscid interaction. The speed of upstream disturbances propagation as a function of ... See full document

... Cuckovic-Dzodzo et al. [269] made a numerical and experimental study on the laminar conjugate natural convection flow and heat transfer in a cubic enclosure with and without a heat conduct- ing partition with glycerol as ... See full document
