Turbulent dispersed two-phase flows are abundant in both industry and nature. The ability to
predict the behaviour of this type of flow - either using numerical or theoretical models - will
be benificial to a wide range of disciplines. However, a lack of consistent experimental data
currently makes validation of both numerical and theoretical results difficult. The main aim
of this thesis is to generate experimental data that could fill this void. In order to do so, a
facility is built to generate isotropic, homogeneous turbulence. This is done using a grid in a
vertical water channel. This new facility is validated and documented for the particle-free case
using Laser Doppler Anemometry (LDA) and Particle Image Velocimetry (PIV). The results
of both measurement techniques are in good quantitative agreement, and the flow is a close
approximation of decaying homogeneous, isotropic turbulence.
