Dynamic Characteristics of Fluid Temperature Between Inlet and Outlet of a Room : 1st Report, The Case of Two-Dimensional Room

Abstract

As the 1st report on the dynamic characteristics of fluid temperature between inlet and outlet of a room, a two-dimensional room with various relative positions of inlet and outlet is treated. First, a mathematical model describing the characteristics of fluid flow in the room is determined experimentally in as simple a form as possible. Next, when the heat transfer into the wall is theoretically added to the above flow model, a mathematical model describing the dynamic characteristics of fluid temperature is obtained. The mathematical model is examined and discussed by experiments. The main results are as follows. The flow model explains well the phenomenon of fluid flow in the room, and parameters in the flow model agree almost with the values estimated by observations of flow patterns. Moreover, the theoretical results of fluid temperature agree well with the experimental ones.
