Experiments on pipe flow and open-channel flow and water surface waves will be conducted for basic phenomena in hydraulics. Programming practice will be conducted for basic problems in the fields of river, coast, and hydrology. | |||
| Course Goals | Through basic measurement, observation of hydraulic phenomena and computational experience using numerical models for fluid flow, students will obtain a fundamental understanding for investigating physical phenomena of fluids. | |||
| Schedule and Contents |
Introduction to hydraulic experiments [Lec: 1time]: The purpose and contents of hydraulic experiments are outlined and the cases related to the ethics of engineers are explained. Overview of the current status of hydraulic experiments, including measurement devices used in hydraulic experiments and the latest experimental facilities, are outlined. The following four experiments (A through D) are conducted in small groups on a rotation basis. Students are required to write a report on each experiment and are instructed on the submitted reports. A) Transition from lamiar to turbulent flows, friction law in pipe flows [1time]: The patterns of laminar and turbulent flows in a pipe are confirmed by the dye injection method. In addition, the Hagen-Poiseuille flow in laminar flow and the Prandtl-Karman flow in turbulent flow are examined in terms of the resistance law. B) Velocity and free-surface profiles in open-channel flows [1time]: Water surface profile and velocity distribution in open channel flow are measured and compared with theories on the resistance law and velocity distribution in uniform flow. In addition, water surface profile in a channel with varying channel gradient is measured and the theory by one-dimensional analysis method is verified. C) Hydraulic jump in horizontal bed [1time]: The most basic hydraulic jump on horizontal roadbed is targeted, and the phenomenon itself should be grasped and the experimental values are compared with theoretical ones by one-dimensional analysis. D) Transmission and deformation behaviors of waves [1time]: Wave profile, celerity, trajectory of water particles, and amplitude of waves propagating in uniform depth are measured. Then, we compare these quantities with the calculated values based on the small amplitude wave theory. In addition, the wave breaking height/depth on the slope are measured and compared with the conventional experimental formula for wave breaking. For the following four experimental items (1 to 4), the basic properties of the phenomena, mathematical expressions and their discretization are explained. Students are required to create a program, perform the calculations, and write a report. Students are instructed on the submitted reports. 1) Numerical solution of the advection-diffusion equation 2) Tracking of open channel water surface profile 3) Refraction of water surface waves 4) Runoff analysis Basic properties of phenomena, mathematical expressions and their discretization are explained in the lecture [Lec: 2times]. Achievement confirmation: [1time], 15 lessons (3 lectures, 11 experiments/practices (including report guidance), 1 Achievement confirmation) |

| Evaluation Methods and Policy | Grades will be based on the experiment and programming practice reports (60 points for the four experiment reports and 40 points for the four programming practice reports, for a total of 100 points). Reports submitted without participating in the experiments will not be evaluated. | |||
