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...

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...

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...

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...

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...

In this paper, echo-PIV and UDV technique were applied to measure the velocity fields of a pipe flow system. The working fluid is mixture of water and kaolin particle. The flow rate of mixture is 0.15 lpm. The error of peak velocity between echo-PIV and UDV were obtained and compared with the theoretical values. This study indicates the...

ISO19152 international standard, led by ISO/TC211 in the meantime, has been published as an international standard at the end of 2012. It does not necessarily mean a simple document published. The FIG having the initiative in international standards-based technology is actively promoting overseas business in developing countries through...

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 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...

Recently, due to rapid urbanization, industrialization and population growth, the structures of cities are changing rapidly; multi-purpose three dimensional facilities above and below surface have been increased. Despite the three dimensional space registration such as building and basement facilities is necessary, it is impossible to represent...

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...
