An Application Example of Fluid Analysis to a Depth Gauge

Abstract

  In this paper, as one of our CAE approaches, we will report fluid analysis results on the water filling process of a depth gauge installed in a divers watch. The analysis was conducted by applying boundary conditions, assuming a sudden water entry during boat diving. As a result, we found that an L-shape in the flow path will easily trap air bubbles. Such CAE approach to predict the behavior of the water flow beforehand contributes to our efforts toward a front-loading design method.
