Abstract Mars atmospheric global circulation models exhibit transonic jet streaks during northern winter, which motivates this study of the Mach number, Ma (the ratio flow speed to sound), and Froude Fr buoyancy waves), as a function season location. Two reanalyses spanning Years (MY) 24 32 are used input, EMARS OpenMARS. The study’s vertical coordinate is potential temperature, θ , ranging fro...

This work presents a summary of data on debris-flow monitoring stations focusing the surge scale rather than full-scale event (several fronts and surges with intermediate diluted flows). Surge-scale are not easily accessible for modellers but would be very beneficial community. A processing protocol is offered, its application to station R?al Torrent described (drainage area: 2 km , SE France)....

A mathematically defined Wigley hull form is used to investigate the application of a commercial CFD code in prediction of the total resistance and its components from tangential and normal forces on the hull wetted surface. The computed resistance and wave profiles alongside the hull were compared with experimental observations for six different Froude numbers to validate the simulations. The ...

An experimental investigation on effect of end sill on the performance of stilling basin models for a non circular pipe outlet has been presented in this research paper. New physical models for non circular pipe outlet stilling basin have been developed in the laboratory. These newly models were tested in the laboratory for three Froude numbers namely Fr = 1.85, 2.85 and 3.85. The new models ar...

We studied nine adult horses spanning an eightfold range in body mass (M(b)) (90-720 kg) and a twofold range in leg length (L) (0.7-1.4 m). We measured the horses' walk-trot transition speeds using step-wise speed increments as they locomoted on a motorized treadmill. We then measured their rates of oxygen consumption over a wide range of walking and trotting speeds. We interpreted the transiti...

A comprehensive methodology to assess the hydrokinetic potential of a reach of the Tanana river near Nenana, Alaska, is developed to help determine the suitability of the reach for installing and operating hydrokinetic electric turbines. The methodology utilizes field measurements and two-dimensional model simulations to define the discharge, velocity, power density, turbulence, and Froude numb...

We study the stability of the steady waves forced by a moving localised pressure disturbance in water of finite depth. The steady waves take the form of a downstream wavetrain for subcritical flow, but for supercritical flow there is a solution branch for each specified forcing term, which has two localised solitarylike solutions for each Froude number, a small-amplitude and a large-amplitude s...

During walking, when both feet are on the ground (the double contact phase), the legs push against each other, and both positive and negative work are done simultaneously. The work done by one leg on the other (W(int,dc)) is not counted in the classic measurements of the positive muscular work done during walking. Using force platforms, we studied the effect of speed and age (size) on W(int,dc)...

Near wakes behind a sphere in both homogeneous and linearly stratified background were studied numerically and experimentally at Reynolds number Re ≤ 1000, Froude number Fr ≥ 0.5. In a homogeneous fluid, the structural transitions with increasing Re are consistent with previous studies. The stratified results from simulations and experiments are in good agreement. Stratified wakes undergo simil...
