Abstract
The flow of gas in a channel with division of the flow by a longitudinal baffle is characterized by the ratio m of the flow rates in the exterior (Ge) and interior (Gi) parts of the channel: m = Ge/Gi. For example, flow in a channel with a wall screen forming a narrow annular slit with the channel wall corresponds to m ≪ 1. In the case of a gas extraction pipe in the channel m ≪ 1. In two-profile gas turbine engines m is of the order of unity or several units [1]. Flow in a channel with a baffle is characterized by the presence of a “liquid” boundary between the flows up to the start of the baffle. For given shape of the channel and baffle, the position of the separating stream surface depends on the conditions of the problem. In the present paper, the influence of the flow rate ratio m on the flow pattern in such a channel is investigated numerically.
