| Abstract: | We set up a diaphragmless driver section as the first step towards developing a shock tube at microscale which has high experimental
efficiency, independent of tube dimensions or the ratio of driver and driven pressure. The experiment described in this paper
is performed by using our diaphragmless driver section. We measured the operating time and the velocity of the fast opening
valve. Additionally we have introduced and calculated the differential equation, by using the Runge–Kutta–Gill method, to
understand the motion of the fast opening valve. We achieved good agreement between experimental and calculated results for
the velocity. We can conclude that the diaphragmless driver section is highly suitable for a narrow channel shock tube.
