Zusammenfassung: | When the isothermal heated rib that was placed on lower plate of the horizontal paralleltwo plates is one piece or more than one, the flow pattern in the channel of two parallel plates, and the natural convection heat transfer coefficients of the surface of the ribs were experimentally studied. The flow pattern was visualized by inserting the tracer particle in equipment, and then inserting the slit light from the side of the equipment. The heat transfer coefficients of the surface of the ribs were decided from visualization of thermal field using the shadowgraph optical method. From above thing, by making rib more than one piece from one piece, it studied what influence the ribs outside gave the heat transfer coefficients of the central rib. |
