鉛直平行平板聞の自然対流場に生ずる準定常流動に関する研究

Quasi-steady multicellular natural convection is induced in a vertical slot filled with glycerin-water solutions and examined by visualizing the flow field and measuring the thermal field. In the experiment, three-dimensional traverse equipment is controlled by a microcomputer and the thermal field in the vertical slot is measured by a thermocouple attached to the traverse equipment. During the measurement, the flow field is observed with aluminum tracer particles in a light sheet and the measuring points are monitored by a video camera. Moreover, methylene blue solution in a glycerin-water mixture is continuously injected in the convection field through a thin hypodermic needle, and the multicellular convection field induced in the vertical slot is revealed.
