Flow visualisation of the wake of a scale pedalling cyclist

Posted by james venning

At Monash we built a 1:4.5 scale-model cyclist that can pedal in order to study the dynamics of the cyclist's wake while pedalling and also to look at the quasi-steady assumption made in [1. T. N. ... Read More

Here we have some visualisation of the wake of a normal flat plate. The plate is quasi-two-dimensional (spans the water channel). It has very sharp edges to reduce Reynolds sensitivity to the thicknes... Read More

In fluid dynamics some quick flow visualisation can often reveal a lot about the flow. Here we have dye injected into the upstream flow of the water channel. You can see two parallel streams on the ve... Read More

Flow separation at front end of Ahmed body.

Some dye visualisation of the Ahmed body at low Reynolds number (Re_L = 26000). This simple experiment shows the scale, location and shape of the separated region. Additionally, we can see some vortex... Read More
