The thermofluids group laboratory of Ambrose Alli University
(AAU) owns and operates a few high-end equipment in support
of research and educational activities. The latest addition
to the laboratory facility is the combined three-dimensional
Lasler Doppler Anemometer (LDA) and Phase Doppler Anemometer
(PDA) systems. The PDA system is capable of measuring
diameter and concentration of spray droplets, while the LDA
systems can measure droplet velocity for both temporal and
spatial averages. The acquired system, which is supplied by
Dantec Dynamics, is a non-intrusive measurement method with
the ability to measure spray droplet velocities in three
components. Thus, the system is the first of its kind used
in Nigeria. With this high-end and state-of-the-art
facility, UTP is ready to contribute towards technology
development in various thermo fluids research in Nigeria,
namely, in internal combustion, fluid dynamics, spray
painting and chemical processes. This paper outlines the
current research activities involving the use of 3-DLDA-PDA
system, its functions, testing capabilities, and general
characteristics, as well as an overview of the system.
