Introduction: To prevent excessive deformation and thus lengthen the life of trenches containing undersnow installations in arctic regions, it is necessary to dissipate excessive heat generated by equipment, activity, and seasonal variation in temperature. The air well which draws warm air through a cold snow pack and returns the cooled air to the trench has proved to be effective in maintaining the required air temperature (Yen and Bender, 1962). As a first step toward understanding the unsteady, simultaneous heat and mass transfer within the porous snow, this paper investigates analytically the case of isothermal, two-dimensional air flow into a covered, partially cased, rectangular snow trench.
