Experiment and Practice in Mechanical Engineering
This course as well as "Experiment in Mechanical Engineering" deals with several kinds of engineering experiments related
to the fundamental topics in the mechanical engineering fields (Mechanics of Materials, Hydrodynamics, Thermodynamics, Mechanical
Vibrations and Control Engineering). Students control experimental apparatuses by themselves and recognize the physical phenomena.
Students have to attend the first lecture. For reference, the themes conducted in 2017 are introduced as follows.

| Each group conducts the following themes in accordance with the schedule. Students need to prepare their lesson referring to following. Reports should be submitted within one week from the date of completion of experiment. Submitted reports are checked by teaching staff. Students have to resubmit the corrected report by the specified day. All the reports have to be submitted to pass the course. | ||
| （１）Mechanical vibration（Saeki) This experiment demonstrates the harmonic response of a system having one degree of freedom. Students learn data acquisition, vibration measurement techniques and application of the knowledge to solving vibration problems. |

| （２）Measurement of boundary layer along a plate (Tsunoda) When a viscous fluid flows along a solid object, a narrow region in which the fluid velocity changes rapidly is formed adjacent to the solid surface. This region is called a boundary layer. The boundary layer which relates to mass and heat transfer between the fluid and the object is one of the important phenomena in fluid mechanics. In the present experiment, students will measure the velocity profiles in the boundary layer on a flat plate in a uniform flow and compare them with theoretical results. The aim of this experiment is to understand a concept of the boundary layer. |

| (3) Boiling heat transfer (Yahagi) Effective utilization of thermal energy is one of the important tasks of mechanical engineering. In order to use the thermal energy effectively, it is very important to know how heat is transferred. In this experiment, we will study a heat transfer mechanism by using the boiling heat transfer phenomena utilizing phase change. |

| (5) Ultrasonic characteristics and nondestructive inspection(Sakaue) Ultrasonic measurement is widely used for nondestructive inspection in engineering feild. In this experiment, the propagation characteristics of ultrasonic in solid material is theoretically studied and is confirmed by experimental measurement. Then, ultrasonic charactristics is applied to nondestractive inspection. |

| 6) Flow in pipe and friction loss (Suwa) In designing of fluid transport system, pumps should be properly selected based on the evaluation of friction loss head against flow. In this experiment, tube friction losses in circular tube in laminar, turbulent and transient region are measured, and the relation between the friction factor and the Reynolds number is studied. This relation is studied also theoretically. |

| (8)Experimental evaluation of combined heat transfer (Yamada) As engineers, it is important to understand the heat transfer. For understanding, we need to categorize heat transfer into three main heat transfer modes. Then, we can use the rate equations that quantify the amount of energy in each mode. In this experiment, students will learn heat transfer modes, principle of temperature measurement and how to categorize heat transfer in one dimensional system. |
