| 概要 |
Since thermal comfort on human body is influenced by the local air flow speed, it is needed to estimate the distribution of air flow speed in a room for the "effective ventilation". Numerical solutio...n of the equations for the motion of 3-dimensional turbulent air flow and model experiments are conducted for this purpose. The experiment model is a single room model house with 2 windows on the opposite walls. It is actually ventilated by the natural wind. Non-directivity thermistor anemometers are used to measured the 3-dimensional distribution of indoor air flow speed. Several kinds of numerical simulation are carried out on the similar space to the experiment model. Two kinds of mathematical turbulence model are adopted, one is the k-ε 2-equation model, and the other is the Large Eddy Simulation. Two kinds of pseudorandom number are used as the turbulence component of the velocity on the inflowing opening boundary in the LES. The distributions of scalar speed of the numerical simulation results in the sections which are perpendicular to axes are compared with those of the experiment results. They are not entirely corresponding, howerver, the same tendencies are found.続きを見る
