Pressure Sensitivity of Buttock and Thigh as a Key Factor for Understanding of Sitting Comfort

Applied Sciences, 2022
In seating comfort research, it is known that the pressure should not exceed a certain threshold from the viewpoint of tissue compression and should be widely distributed. However, its ideal distribution is not defined in past research.

Study of Flow Characteristics around a Near-Wall Circular Cylinder Subjected to a Steady Cross-Flow

International Journal of Coastal and Offshore Engineering, 2018
Three-dimensional RANS simulations are employed numerically to study flow characteristics around a near-wall circular cylinder for varying gap-to-diameter (G/D) ratios (Where G is the gap between the cylinder and the wall and D is the cylinder diameter ...

Simulation of Water Influx and Gasified Gas Transport during Underground Coal Gasification with Controlled Retracting Injection Point Technology

Energies, 2022
Underground coal gasification (UCG) may change the energy consumption structure from coal-dominated to gas-dominated in the years to come. Before that, three important problems need to be solved, including failure of gasification due to large amounts of ...

Sunspots and Pressure Distribution [PDF]

Nature, 1930
THE issue by the Meteorological Office of the daily charts of the weather in the northern hemisphere has enabled me to ascertain the barometric changes which take place from day to day in high latitudes. As a rule, the cyclones and anticyclones are large as compared with the polar uncharted area, and it proved possible to extend the isobars of the ...

Optimal Design of a Plenum Fan with Three-Dimensional Blades

Applied Sciences, 2020
We successfully designed an optimized plenum fan with a three-dimensional, smooth, curved blade. The optimized model revealed that the static pressure in the channel had been increased uniformly and stably, and the flow separation at the leading edge was
