We are planning an experimental and computational study investigating the influence of background rotation on the flow physics of vortex rings. The corresponding non-rotating flow represents one of the classic paradigms employed to study fundamental vortex dynamics. Probably as a consequence of the extremely limited number of sufficiently large rotating turntables available worldwide the flow which we plan to investigate has possibly only been considered in one single previous investigation (see case for support). These previous authors have identified several pronounced effects of rotation on the vortex rings but could not study them in detail due to limitations of their experimental equipment. At Warwick we have recently built on eof the largest and technically most advanced turntables in Europe. This turntable will form the basis for the design of a significantly superior experimental facility. We will carry out detailed experiments on rotating vortex rings and com-pare our results to the extensive literature on the non-rotating flow. In parallel with the experiments we will carry out computations utilising our recently developed novel, fully 3D, discrete-vortex method. We anticipate being able to simulate numerically, for the first time, the influence of background rotation on phenomena such as the classic wavy vortex ring instability.
