Flow Visualization and Image Measurement around Bridge Beams

Abstract

Okinawa is subtropical islands and is enclosed in the ocean. There is a problem that corrosion of the structures progresses quickly because of sea-salt mist flying from sea. In this paper, The Authors investigate the relationship between corrosion and flow structures around the bridge beams as structures. Therefore, PIV is used to clarify the flow structures within the bridge beams and the corrosion within the bridge beams is guessed by a numerical approach by means of momentum equation of sea-salt particles.
