Kappa Carrageenan

The spatially resolved spray characteristics created by the like-on-like impingement of two gelled propellant simulants was experimentally investigated using Phase Doppler Anemometry (PDA). Water based gels of 1.0 wt.-% agar and 1.0 wt.-% kappa carrageenan, which were characterized using the Herschel-Bulkley rheological model, were used as the gel propellant simulants. Spatially resolved measurements for drop size and drop velocity were obtained up to 10 mm away from the centerline along the transverse axis in the plane of the sheet and up to 20 mm away from the centerline along the transverse axis in the plane normal to the sheet. All measurements were obtained at an axial plane 5 cm downstream of the impingement point. Larger D10 and D32 mean diameters and lower mean axial drop velocity Uz-mean were observed for transverse distances away from the centerline of the spray along both the axis in the plane of the sheet and in the plane normal to the sheet.
