AbstractWe present a method for creating a new type of model particle that allows us to measure the mass transfer rate from the particle surface to the surrounding water. We use hollow glass spheres and sugar to create neutrally buoyant particles in a variety of molded shapes. These particles are an alternative to traditional gypsum objects for measuring mass transfer, with the important characteristic of being neutrally buoyant. This is an inexpensive method that allows for custom particle shapes to be manufactured with different densities. We test the utility of these particles by measuring their dissolution rates in homogeneous, isotropic turbulence in our laboratory turbulence tank. Our measurements fit our proposed model, and give a faster dissolution rate for rod-shaped particles than for disc-shaped ones.Graphic abstract
