Spatiotemporal dynamics of the atmospheric kinetic energy and its components caused by ordered turbulent motions air masses are estimated from minisodar measurements three velocity vector their variances within lowest 5–200 m layer atmosphere, with a particular emphasis on energy. The layered structure total has been established. From diurnal hourly altitude profiles (TKE) retrieved data, four ...

Abstract Tightening noose on engine emission norms compelled manufacturers globally to design engines with low specially NO x and soot without compromising their performance. Amongst various parameters, shape of piston bowls, injection pressure nozzle diameter are known have significant influence over the thermal performance emanating from engine. This paper investigates combined effect fuel pa...

Abstract This study examined characteristics of near-inertial internal waves (NIWs) associated with the background mesoscale field near Tsushima Warm Current. Observational stations off Sado Island were visited recurrently to assess spatiotemporal changes fine-scale and microscale properties seawater. Also, NIWs inspected in terms relative vorticity total strain surface geostrophic motion. Duri...

Obstructive Sleep Apnea (OSA) is a breathing disorder that occurs during sleep. This syndrome affects numerous people, especially those with abnormal body fat composition parameters such as mass index (BMI) of more than 25 kg/m2 (overweight & obesity). OSA ensues when the tongue and soft palate muscles in relaxed condition move towards gravity patient supine position; this causes narrowing ...

Outlier detection for PIV velocity fields is still nowadays an active field of research. In the last decades, several image pre-processing and processing algorithms have been developed aiming at increasing dynamic range measurements reducing measurement uncertainty. Nevertheless, are often characterised by presence outliers, which potentially hamper correct interpretation flow physics negativel...

A new experimental–theoretical framework has been developed to investigate turbulence and modulation in a two-phase multicomponent particle–liquid flow mechanically agitated vessel. discrete wavelet transform is used decompose long-term three-dimensional Lagrangian trajectories of phases, acquired by technique positron emission particle tracking, into their deterministic stochastic sub-trajecto...

Macroalgae, with their various morphologies, are ubiquitous throughout the world’s oceans and provide ecosystem services to a multitude of organisms. Water motion is fundamental physical parameter controlling mass transfer dissolved carbon nutrients from macroalgal surface, but measurements flow speed turbulence within above canopies lacking. This information becoming increasingly important as ...

Abstract Horizontal organization or mesoscale variability is an important mechanism in the interaction of boundary layer with large-scale conditions. The development a precipitating cumulus trade wind studied using large-eddy simulations extensive horizontal domains, up to 160 × km 2 and fine grid resolution (40 m). cloud fields vary between different computational domain sizes. Mean profiles v...

As the average hub height and blade diameter of new wind turbine installations continue to increase, turbines typically encounter higher wind speeds, which enable them to extract large amounts of energy, but they also face challenges due to the complex nature of wind flow and turbulence in the planetary boundary layer (PBL). Wind speed and turbulence can vary greatly across a turbine’s rotor di...

Accurately measuring the critical shear stress is crucial for numerous applications, such as sediment transport modeling, erosion prediction, and design of sustainable coastal engineering structures. However, developing reliable precise in-situ measurement devices faces significant challenges due to harsh dynamic nature aquatic environments. Factors like turbulence waves introduce complexities ...
