OSA | Structure Design of Microchannel Water-cooled Mirror

Reducing hydraulic diameter may help to induce high heat transfer coefficient. The trapezoid channel mirror has the smallest thermal deformation among the three shapes channel mirrors. At the condition of heat flux of 1.47W/cm2, and water inlet velocity of 2.54m/s, the thermal deformation of mirror with the smallest trapezoid microchannel is only about 1.6×10−2μm. numerically.

Diameter - Wikipedia

In geometry, a ,diameter, of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the ,diameter, of a sphere.. In more modern usage, the length of a ,diameter, is also called the ,diameter,.
