Heat transfer by seepage in sand: Influence of saturated hydraulic conductivity and porosity

Heat transfer within the soil is a complex process in presence of seepage flow. In such conditions, soil’s thermal behavior influenced by and hydraulic properties medium as well initial conditions boundary to which subjected. This paper presents experimental numerical studies heat sand subjected It focuses on influence saturated conductivity porosity process. The temperature distribution was monitored optical fiber Distributed Temperature Sensor (DTS). experiment performed three types silica-dominated sands with different conductivities Soil Water Characteristic Curve (SWCC). addition study, coupled hydrothermal model designed FEFLOW software validated comparing its results measurements. To determine transfer, we analyzed models for values conductivity. showed that velocity higher declination occurs more quickly due convection Saturated larger has an overall capacity, wherefore started later measuring points but dropped down lower close upstream water.
