Determination of the aerodynamic configuration of wake is the key to analysis and evaluation of the rotor aerodynamic characteristics of a horizontal-axis wind turbine. According to the aerodynamic configuration, the real magnitude and direction of the on-flow velocity at the rotor blade can be determined, and subsequently, the aerodynamic force on the rotor can be determined. The commonly employed wake aerodynamic models are of the cylindrical form instead of the actual expanding one. This is b...

Abstract This paper is an investigation on oscillation characteristics and transition routes of thermocapillary convection in an annular liquid pool in the space experiment carried out on SJ-10 recoverable scientific experiment satellite. Thermocapillary convection caused by non-uniformity of surface tension and the instability problem of the convection are introduced, and the measurement by thermocouples has been analyzed in detail. Through the relationship between the critical condition of sta...

The oscillation of liquid/gas free surface in a partially filled storage tank caused by an abrupt drop of gravity level is of critical importance for the fluids management in space. In present study we investigate the dynamic behavior of free surface in tank models (tubes) using water as the working medium utilizing the Drop Tower Beijing, which can provide a 3.6s short-term microgravity condition. Meanwhile, the corresponding numerical simulation using volume of fluids (VOF) methods was carried...

To analyze the interaction between wind turbines and the atmospheric boundary layer, we integrated a large-eddy simulation with an actuator line model and examined the characteristics of wind-turbine loads and wakes with reference to a corresponding experiment in Gansu. In the simulation, we set the wind turbine to have a rotor diameter of 14.8 m and a tower height of 15.4 m in the center of an atmospheric boundary layer with a 10.6° yaw angle. The results reveal an obviously skewed wake structu...

Experiments and numerical simulations of the wake field behind a horizontal-axis wind turbine are carried out to investigate the interaction between the atmospheric boundary layer and a stand-alone wind turbine. The tested wind turbine (33 kW) has a rotor diameter of 14.8 m and hub height of 15.4 m. An anti-icing digital Sonic wind meter, an atmospheric pressure sensor, and a temperature and humidity sensor are installed in the upstream wind measurement mast. Wake velocity is measured by three U...

Thermocapillary convection has always been a hot topic of great importance in either crystal growth or thin films science. A space experiment about thermocapillary convection in an open cylindrical annuli pool will be done on SJ-10 satellite. A payload for space experiment has been established, which includes a cylindrical annuli thermocapillary convection system, a thermocouple temperature controlling system and measurement system, a thermal infrared imager, a high-precision displacement sensor...

As a part of the preliminary studies for the future space experiment (Zona-K) in the Russian module of the International Space Station, some bifurcation routes to chaos of thermocapillary convection in two-dimensional liquid layers filled with 10 cSt silicone oil have been numerically studied in this paper. As the laterally applied temperature difference is raised, variations in the spatial structure and temporal evolution of the thermocapillary convection and a complex sequence of transitions a...

Gravity affects the stability of Marangoni flow in floating half zone of low-Pr fluids through two different factors, i.e., the buoyancy and the static deformation of the free surface shape. In the present study, influence of these two factors are evaluated by unsteady three-dimensional (3D) simulations for a realistic model of floating half zone of molten tin (Pr = 0.009) with an aspect ratio As = 2.0 under a ramped temperature difference (1.19 K/rnin) between the top and bottom ends of two iro...
