MALVERN TEST:

-The Spraytec Malvern Particle Analyser was used to characterize the flow and to ascertain various physical and flow properties of the particles in the simulated ACM icing conditions generated by the rig. 

-The Malvern is setup by attaching the two main components, the transmitter and the receiver on the balancing beam or the optical bench that keeps the two modules aligned with the focus of the acquisition lens focused near to the centreline of the exhaust. 

-The Malvern is capable of measuring across a wide size range (0.1 – 2000 microns) without requiring constant optics changes. 

-It makes use of laser diffraction for measurement of the size of spray droplets and spray particles. It does this by measuring the intensity of light scattered as a laser beam passes through a spray. 

-This data is then analysed to calculate the size of the droplets that created the scattering pattern. For this particular application, the 300mm lens was chosen as it’d cover the necessary range of droplet sizes expected within the flow (0.1 – 900 µm (Dv50: 0.5 – 600 µm)).
