Research convection heat exchange in the cable channel, laid in the earth

The mathematical model of processes convection heat exchange in the cable channel, laid in the ground without taking into account the thermal radiation. Shows the dependence of temperature on the surface of the cable division into finite elements Fields the trajectory of particle motion in the cable channel, the temperature field. Shows the dependence of temperature on the surface of the cable channel on the thermal conductivity of various structural elements in the cable channel.
