2-1. Object
Passive cooling techniques are key technologies (ex. nuclear reactors), because these can drastically improve the safety and reliability of the reactors.
=> Techniques that increase the natural convection heat transfer rates should be developed.
* previous techniques
techniques and devices
shortness
use a finned surface
thicknesses become very large
install promoter
(small roughness elements,
rectangular ribs)
no appreciable increase
in heat transfer rates

Present authors have proposed a unique type of promoter : "V-shaped" is the best.
And they experiment to find adequate "height and angle"

2-2. Experimental Apparatus and Measurements
*Apparatus
- heat transfer plate and side plate
- V-shaped promoter(1mm thick vinylchloride resin plate)
- fluid : water
The whole apparatus was submerged
