final year PhD candidate
University of Edinburgh
My name is Krisna Adi Pawitan, M.Sc. and I am a final year Ph.D student from the Institute for Energy System, University of Edinburgh. My thesis focused on the oscillating water column integrated into a vertical breakwater. The aim to the study are reducing the uncertainty in the water column behaviour, including the wave loadings model for the inside chamber caisson and the water column condition during operation, and the small-scale scaling effect. Just like other coastal structures, Froude scaling similitude is ussually followed for an OWC installed breakwater small-scale physical model testing. This scaling method, however, ignored the air chamber compressibility different between the prototype and the small-scale model. Since the air volume in the small-scale is significantly smaller ( cubic of the scale), the air inside the chamber may becomes incompressible. The thesis aims to look for a scaling effect by comparing a large-scale and small-scale physical model experiment results.
I got my master degree from National Taiwan University of Science and Technology (NTUST). For my master, i did a flow visualisation of a jet in cross-flow. the experiments involved a high-speed camera and smoke particle generator to show the turbulent flow when the jet is mixing with the cross-flow air. I did my bachelor degree in the Institute Technology of Bandung (ITB), Indonesia. The final bachelor degree project involved a numerical analysis of a novel jet engine's compressor designed by Dr. Firman Hartono.
