Iowa State's icing wind tunnel blows cold and hard to study ice on wings, turbine blades（图）
wings turbine blades Iowa State's icing wind
2014/3/20
Iowa State engineers have refurbished an icing wind tunnel and are using it to study ice buildup on aircraft wings and wind turbine blades. Ice on the wings and blades can be dangerous and costly.
Predicting Stem Windthrow Probability in a Northern Hardwood Forest Using a Wind Intensity Bio-Indicator Approach
Windthrow Prediction Species Wind-Firmness Tolerant Hardwood Forests Silviculture Guidelines
2013/3/4
Unlike fire or insect outbreaks, for which a suppression program can be implemented, it is impossible to prevent a windstorm event or stop it while it is occurring. Reducing stand susceptibility to wi...
Influence of Cover Crop Seeding Date and Their Amounts on Mitigation of Wind Erosion
wind erosion cover crop
2010/12/2
Soil wind erosion is a serious issue in upland fields, because winter fallow treatments produce awful erosions in Kato area, Japan. This research evaluated the abilities of cover crops that planted at...
A New Instrument for Testing Wind Erosion by Soil Surface Shape Change
Wind Erosion Soil Surface Shape Change
2009/12/2
Wind erosion, a primary cause of soil degeneration, is a problem in arid and semiarid areas throughout the world. Many methods are available to study soil erosion, but there is no an effective method ...
Effects of Side Vents and Span Numbers on Wind-Induced Natural Ventilation of a Gothic Multi-Span Greenhouse
CFD greenhouse design optimization
2009/9/10
In this paper, the effects of wind speed, side ventilators and span numbers on gothic type multi-span greenhouse natural ventilation were studied by numerical simulation using the Computational Fluid ...
Analyses of Wind Damage Caused by Typhoon 200221 at Shelterbelts in Tokachi,Hokkaido
shelterbelt species stand age stand density thinning
2009/8/28
By analyzing the wind damage caused by the typhoon 200221 at shelterbelts of Tokachi in Hokkaido, it was found that tree species, orientation of shelterbelts, stand age, and species of windward sub-co...
Complex Influence of Wind and Topography in Predicting Area of Fire Spread for Forest Fires: As Exemplified by a Forest Fire in Kakamigahara City
forest fire Kakamigahara City spread topography wind direction
2009/8/28
The spread of forest fire is largely related to wind and topography. What is most important is the relationship between wind direction and topography in predicting the area of fire spread since the ma...
Mechanical Evaluation of the Japanese Larch for Wind Damage
tree pulling angle of inclination diameter at breast height maximum resistive moment mode of failure
2009/8/21
To evaluate the mechanical stability of the Japanese larch (Larix kaempferi Carr) against wind loading, tree-pulling experiments were conducted in Tokachi, Hokkaido. The Japanese larch forests of this...
Combined Effect of Hill Arrangement, Wind Direction and Wind Speed on Bending Angles of Culms and Lodging Levels in Rice Plant
Bending angle Lodging level Major axis of a rice hill Rice hill Wind direction Wind speed
2009/8/6
This experiment started from the observation that the cross section of a rice hill was ellipse in shape. When two rice plants cv. Koshihikari were transplanted in a 1/2000 are Wagner pot, the rice hil...
Decrease of Leaf Water Potential and Leaf Injury of Tea Plant (Thea sinensis L.) Subject to Cold Winter Wind in Sanin Region of Japan : II. Increase of water flow resistance inside the plant contributes to decrease of leaf water potential
Cold wind injury Leaf water potential Transpiration rate Water flow resistance Tea
2009/8/4
In the previous report, we indicated that cold wind injury of tea leaf in Sanin region occurred under decreases of leaf water potential (ΨL) caused by low temperature and strong wind. We attempted to ...
