Abstract
Cold water introduced with a low flow rate into a duct filled with hot water normally circulates in the bottom thereof and accumulates at its end. It is discharged only at the end of the distributor where its pressure is highest. The immiscible hot water is located elsewhere and high thermal stresses appear on the distributor at the interface between two layers. This problem is solved by providing the distributing tubes (2) or the actual duct (1) with cuts (6 and 9) in particular favoring the upstream flow.
