Niels’s Bachelor thesis project started off from an observation of a ‘‘defective’’ ice ball melting in our dodecahedron setup . The sphere had an equatorial groove, and Sander Husiman and I developed a project to investigate how would the groove evolve throughout the melting time. Hence, Niels casted grooved ice balls out of silicon moulds, and melted them under isotropic turbulence in the dodecahedron. He imaged the melting balls, and measured the time evolution of the shape of their grooves, and linked it to the particle’s Reynolds number.

Simon did his Bachelor thesis project with me and Sander Husiman, performing experiments on the problem of melting on an inclined heated ramp. He started off using paraffine wax, which is solid at melting temperature, and continued using ice blocks in a walk-in fridge. He measured the melt rate and velocity of the blocks as a function of the angle of inclination and surface temperature of the inclined ramp.

Yiyu did an internship with me and Sander Husiman while he was a student at the University of Science and Technology of China in Heifei. He worked gathering useful data on the melting of ice balls in turbulence, measuring the melt rate and the shape evolution of spheres that are held in place in the centre of our dodecahedron setup. From the melt rate, he extracted a Nusselt number and investigated its scaling with the particle’s Reynolds number.

Hannah did her Master thesis project with me and Sander Husiman, doing experiments on floating ice cylinders. She measured the melt rate of floating ice cylinders, of different initial sizes and with different ambient water salinities. She tracked the evolution of the cross section of the cylinders in time.
