When viewing the Technical Program schedule, on the far righthand side
is a column labeled "PLANNER." Use this planner to build your own
schedule. Once you select an event and want to add it to your personal
schedule, just click on the calendar icon of your choice (outlook
calendar, ical calendar or google calendar) and that event will be
stored there. As you select events in this manner, you will have your
own schedule to guide you through the week.
You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.
Vehicle shape optimization for reducing aero dynamic drag
SESSION: Aerospace/Automotive
EVENT TYPE: Masterworks
TIME: 2:15PM - 3:00PM
Presenter(s):Tsuyoshi Yasuki
ROOM:TCC 301/302
ABSTRACT: Reduction of aerodynamic drag of car will be more important in foreseeing future. About 35% of aerodynamic drag of two-box type car is occupied by aerodynamic drag on backward face of the car. However, flow behind the backward face of the car is too complex to clarify its structure of flow by wind tunnel tests or non-transient Computational Fluid Dynamics (CFD) due to backflow in the wake, three dimensional vortex tubes, and time dependent stream lines.
Very Large Eddy Simulations (VLES) was employed to clarify structure of flow behind the backward face of the car. The result indicated that backflows generated a vortex tube structure behind the backward face of the car. Parametric studies of shapes of backward face of the car were performed by the VLES and clarified relationships between the vortex tube structures and aerodynamics drag behind the backward face of the car.
