Mesoscopic prediction on the effective thermal conductivity of unsaturated clayey soils with double porosity system

A Fully Coupled THM Double Porosity Formulation for Unsaturated Soils

Experimental Investigation of the Alumina/Paraffin Thermal Conductivity Nanofluids with a New Correlated Equation on Effective Thermal Conductivity

Liquid paraffin as a coolant fluid can be  applied in electronic devices as a result to its suitable capabilities such as electrical insulating, high heat capacity, chemical and thermal stability, and high boiling point. However, the poor thermal conductivity of paraffin has been confined its thermal cooling application. Addition of high conductor nanoparticles to paraffin can fix this drawback...

Effective Unsaturated Hydraulic Conductivity

Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...

Unsaturated Hydraulic Conductivity of Fractal-Textured Soils

A concise parameterization of the hydraulic conductivity of unsaturated soils

The parameter n in the well-known expression for hydraulic conductivity K ˆ K0S e (where K0 is its value at satiation and Se the e€ective saturation) is determined as a function of the exponent in the power form of the soil±water retention relationship. The result is validated with an extensive experimental database comprising some 43 soils, collected by Mualem. Ó 2000 Elsevier Science Ltd. All...
