Thermal properties of a tropical unsaturated soil

investigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers

امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...

Estimation of Unsaturated Soil Properties Using a Knowledge-based System

The Soil-Water Characteristic Curve (SWCC) is an important soil function relating the water content of a soil to soil suction. Many unsaturated soil properties (or soil property functions) can be related to the water content versus suction relationship of a soil. Hydraulic conductivity, shear strength, chemical diffusivity, water storage, unfrozen volumetric water content, specific heat, and th...

Determination of unsaturated hydraulic conductivity by internal drainage assuming a uniform soil water profile

Thermodynamic Basis of Unsaturated Soil Modeling

Upon an increase of moisture, unsaturated soil may collapse or swell, depending on the loading state and history. This important characteristic must be realistically reproduced by a constitutive model aimed for practical applications. In addition to collapse/swelling, other essential features, such as deformation and failure following arbitrary shearing paths, must also be realistically reprodu...

A Method for Microclimate Observation and Thermal Analysis -Tropical Condition of Kuala Lumpur

Using outdoor public spaces as a place of social interaction is in a great consideration these days. Providing tolerable thermal condition as long as possible is one of the primary stage for people’s presence in these places. Outdoor thermal indices are introduced to help architects making appropriate decisions in climate responsive design procedure. By doing some field study research in extr...
