Magnetothermal Wind Visualized by Numerical Computation
This study describes the numerical evaluation of the transient and steady state characteristics of a magnetothermal wind created by the Kelvin force inside the bore space of a super-conducting magnet. The model system designed to evaluate the present ...
Numerical Analyses of Flow around Airfoils Subjected to Flow Induced Vibration
This paper describes extensive computer-based analytical studies on the details of unsteady flow behavior around airfoils subjected to flow induced vibration in turbo-machinery. To consider the time-dependent motions of airfoils, a complete Navier-...
Flow Visualization and Pressure Measurement in Micronozzles
Micro devices have been widely used in aerospace engineering for years. Engineers are interested in applications of micro devices such as microjets, micro actuators, and micronozzles. The small size nozzles can be used for attitude adjustment and ...
Pressure-Sensitive Paint Measurement of the Flow around a Simplified Car Model
In applying Pressure-Sensitive Paint (PSP) to low-speed flow wind tunnel testing, it is important to minimize any measurement uncertainties. There are various error sources such as camera noise, misalignment of images due to model displacement and ...
Controlled Vortex Breakdown on Modified Delta Wings
This paper studies the effect of perturbation to the breakdown of the leading-edge vortices over delta wings. The passive perturbation in the normal direction is achieved by installing the hemisphere-like bulges on the delta wing along the projection of ...
Transition of Free-Surface Flow Modes in Taylor-Couette System
This paper presents our numerical and experimental results of the bifurcation found in Taylor-Couette system with a free surface. The lengths of the two concentric cylinders are finite and their axes are parallel to the direction of the gravitational ...
Self-Induced Rotary Sloshing Caused by an Upward Round Jet in a Cylindrical Container
Jet-induced rotary sloshing of a Newtonian fluid in a partially filled cylindrical container is numerically and experimentally visualized to investigate a flow pattern inside the rotary sloshing wave. Visualization techniques employed in this study ...
Oceanic Water Intrusion into Kagoshima Bay Resulting in Thermal Stratification
Kagoshima Bay is an enclosed bay that has the tendency to undergo eutrophication, and a very important site to describe the behavior of open seawater intrusion. According to the results of the satellite SST (Sea Surface Temperature) image analysis or ...
