Abstract In this research, the trade-off between the number of restrictions and the robustness of the primary formulation of entropy models was evaluated. The performance of six hydrodynamic models in open channels was assessed based on 1730 Laser-Do

A remote sensing technique to detect area-averaged temperature and flow properties within an area under investigation, utilizing acoustic travel-time measurements, is introduced. This technique uses the dependency of the speed of acoustic signals on

Acoustic travel time tomography uses the dependence of sound speed on temperature and flow properties along the propagation path to measure these parameters. An algorithm is introduced that is capable of resolving the two-dimensional flow field withi

Any physical description setting for the distribution of momentum, energy and matter within the turbulent boundary layer of the atmosphere is usually made according to models based on the assumption of horizontal homogeneity. However, the earth's sur

A time-dependent numerical model is developed for the description of icing on an unheated, non-rotating cylinder in supercooled water clouds. The model predicts, with consideration of the effect of roughness and shape, the mass and profile of ice acc

Two different bulk-parameterization schemes of cloud microphysics alternatively used in a meso-ß-scale meteorological model are compared to elucidate their influence on the predicted atmospheric water cycle. The different parameters (e.g., ice cryst
