concrete deformation due to temperature and moisture condition will always develop simultaneously and interactively. the environmentally (hygral and thermally) induced stress and deformation are essential to concrete durability. to simulate the deformation of concrete caused by the coupling effect of temperature and moisture, a numerical simulation approach is proposed comprising analytical pro...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

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...

abstract assessing moisture in the soil under cultivation of crops to achieve high performance and reduced water are necessary. knowledge of the moisture distribution in the root zone, time consuming and costly field tests that simulation models, a suitable alternative in answer to issues of movement and are water distribution. in this study assessment of soil moisture, to aid swap simulation m...

abstract using mathematical models for irrigation management have great impacts to increase irrigation efficiency and product amount, in fields. in this study, simulation results by swap model for moisture, compared with soil profiles moisture values, measured in the field. moisture data, measured at three wheat farms in the neyshabur plain, were used to predict moisture. results show good agre...

drying is an important operational step in pistachio processing. there is a decrease in moisture content of pistachio nuts from 56-57% (d.b.) to 5-6% during the drying process. drying conditions affect the quality of dried pistachio nuts, therefore, this calls for an accurate description of the drying trend in the process. in this study finite element formulation and solution of diffusive moist...

In this paper, a fast moisture sensitivity level (MSL) qualification method and a fast moisture characterization method are discussed. The fast moisture characterization uses a stepwise method to obtain more reliable and more material moisture properties. The established relationships for moisture diffusion coefficients and moisture saturation levels with respect to the temperature and relative...

Concrete deformation due to temperature and moisture condition will always develop simultaneously and interactively. The environmentally (hygral and thermally) induced stress and deformation are essential to concrete durability.

A trajectory analysis of the CCM3 moisture simulation is used to show that the model simulates uppertropospheric moisture observations better than would be inferred from a traditional geographical comparison. The upper-tropospheric moisture simulation is compared to upper-tropospheric moisture derived from GOES 6.7-micron observations for September 1992. Trajectories start in convective regions...

In this work, internal moisture profiles obtained either by simulation or experimentally during the convective drying of resorcinol-formaldehyde gels are compared. Such a comparison constitutes an attractive way to validate drying simulation models. X-ray microtomography, a powerful 3D imaging technique, coupled to image analysis is used to determine the internal moisture profiles in a non dest...
