Thermal stratification is encountered in large pool of water increasingly being used as heat sink in new generation of advanced reactors. These large pools at near atmospheric pressure provide a heat sink for heat removal from the reactor or steam generator, and the containment by natural circulation as well as a source of water for core cooling...

Three physiological functions of nasal breathing (air-conditioning, filtering and smelling) are closely related with airflow characteristics in the human nasal airway. Since fluid mechanical properties are heavily affected by the geometry of flow passage, the changes in anatomical shape of nasal cavity by disorders or surgical treatments alter...

Contact lines are the locations where a gas, liquid and a solid meet. From everyday experience we know that such contact lines can be mobile, for example in the case of a water droplet sliding over a glass surface. However, the continuum description of the flow towards or away from a contact line implies that the forces diverge as one approaches...

Dynamic behaviour and heat transfer characteristics of impinging droplets on a hot surface were studied experimentally. De-ionized water droplet was made through a 31G injection needle and the droplet size was 2 mm. A sapphire plate was heated up to 300ºC by a hotplate. A high speed camera was used for visualization, and the frame rate was 4000...

Flow inside a scaled model of nasal cavity was measured by tomographic PIV. The model was constructed with transparent silicon. A refractive index of working fluid was matched to the model index by mixing glycerol and water. Four cameras and double pulse laser system were used for tomographic PIV. To obtain high SNR, red fluorescence particles...

We study the dielectric constant dependent diffraction phenomena of single slit apertures, both theoretically and experimentally. We experimentally simulate perfect metal and real metal cases by investigating subwavelength diffraction by a single slit, both in nano-optical and in terahertz regimes, keeping the slit-width/wavelength ratio...

The investigation on the seismic behavior of dams becomes crucial but is limited due to lack of experimental or field data. This paper aims to experimentally simulate the seismic behavior of three types of dams; earth-core rock-fill dam (ECRD), concrete-faced rock-fill dam (CFRD), and composite dam which combines concrete dam and CFRD. A series...

This paper develops a decision-support tool for estimating the balanced market shares of given freight transport systems operating in a given network, satisfying both the minimum costs and the Carbon-Dioxide (CO2) emission requirements. Since CO2 constraints in logistics markets need to be realized in the near future, a modal shift in freight...

The flows in a naturally evaporating liquid droplet confined by two flat plates were investigated experimentally. A diluted sodium-chloride (NaCl) aqueous solution was used to form the confined droplets. The evaporation of water at the free surface of the droplet built up a concentration gradient inside the solution, which induced a natural...

We developed a new education curriculum called "ALPS" (Active Learning Project Sequence) at Keio University that emphasizes team project-based learning and design thinking with systems engineering techniques. ALPS is a 6 month course, in which students work as a team and design and propose innovative systems. Students identify requirements,...

The purpose of this paper is to develop an accurate analysis code for the flow of arc-heater by employing advanced numerical models. Governing equations are hyperbolic-type axisymmetric Navier-Stokes equations which include joule heating by arc, radiation and turbulent transport effect. Joule heating is simply calculated by Ohm’s law with the...

This paper reports a technique for measuring the velocity and dissolved oxygen (DO) concentration fields simultaneously in a micro-scale water flow using oxygen sensitive particles (OSParticles) and a conventional micro particle image velocimetry (?-PIV) method. The OSParticles were fabricated using a dispersion polymerization method by...
