Fall Meeting 2008

The Fall meeting will be held on Wednesday, November 12, 2008, in the Sherwood Room in Levering Hall on the Homewood Campus of Johns Hopkins University at 8:30 p.m. The speaker will be Dr. Charles Meneveau, Louis M. Sardella Professor in Mechanical Engineering and Director of the Center for Environmental and Applied Fluid Mechanics at Johns Hopkins University, Baltimore, MD. He will present a lecture entitled "Modeling turbulent flow over fractal trees using Renormalized Numerical Simulation."

You are cordially invited to attend the pre-lecture dinner with the speaker. See below for directions and parking information for the lecture and dinner.

Lecture

Modeling turbulent flow over fractal trees using Renormalized Numerical Simulation

Dr. Charles Meneveau
Louis M. Sardella Professor in Mechanical Engineering
Director, Center for Environmental and Applied Fluid Mechanics
Johns Hopkins University

I will describe the challenges associated with simulating turbulent flows over complex multi-scale objects. In particular, we consider fractal, tree-like objects, with special emphasis on the drag forces produced. Fractal objects display large scale-disparity and complexity while being amenable to simple and standardized description. Hence, they offer an elegant idealization of the actual interactions between turbulence and boundaries in practical applications where boundaries are characterized by multiple length-scales. In order to avoid the need to resolve all the small-scale branches of the fractal, a new numerical modeling technique called Renormalized Numerical Simulation (RNS) is introduced. Results illustrate that RNS enables numerical modeling of physical processes associated with fractal geometries, using affordable computational resolution.

Dinner

The pre-lecture dinner will be held at Gertrude's Restaurant in the Baltimore Museum of Art, which is next to the Johns Hopkins campus. Dinner will begin at 6:30 p.m. Four entrees are available for your advance selection: Gertie's Crab Cake ($35.00), Marinated Flank Steak ($33.00), Five-Spice Chicken ($33.00), and Thai Vegetable Curry ($31.00). The pricing is inclusive of salad, entree choice, all soft beverages (sodas, coffee, tea, etc.), tax and gratuity.

To attend the dinner, please send your entree choice along with a check for the appropriate amount (made out to SIAM Washington-Baltimore Section) early enough to be received by Friday, November 7, to our Treasurer, Jeff Sieracki, PO Box 1011, College Park, MD, 20741. PLEASE include your full name and email address with your check so that we can send you a confirmation of your reservation. If you cannot get your check to him by that date and you still want to come to dinner, then please email him by Friday, November 7, at jsiam@sr2group.com. Gertrude's can accommodate at most twenty-five diners on this occasion, so be sure to reserve in advance.

Campus Directions

The Homewood Campus of Johns Hopkins University is in Baltimore near 33rd and Charles Streets. The lecture will be held in the Sherwood Room in Levering Hall. Gertrude's Restaurant is in the Baltimore Museum of Art (BMA), which is next to the campus. You may refer to the Homewood Campus and Parking Map, available at http://www.parking.jhu.edu/general_maps.html, for the exact location of both venues.

Driving to BMA from I-695 (points East, North, and West):
Take exit #23 to I-83 South (Jones Falls Expressway). Follow I-83 several miles to 28th Street eastbound exit. On 28th Street, go to the fourth traffic light, and turn left onto North Howard Street. Go one block on Howard Street, crossing 29th Street, and bear right at the fork onto Art Museum Drive. The BMA will be on your left.

Driving to BMA from I-95 or MD-295 (points South):
If coming on the Baltimore-Washington Parkway (MD-295), follow it to the end and you'll be on Russell Street. If coming on I-95, take the Russell Street exit. On Russell Street go over the bridge, exit into the right lane, and follow the signs onto Martin Luther King Boulevard. On Martin Luther King Boulevard go past U.S. 40; get into the center lane. After passing Druid Hill Avenue stay in your lane and bear left onto North Howard Street. Go past North Avenue and continue until you pass 29th Street. Bear around to the right at the fork onto Art Museum Drive. The BMA will be on your left.

Parking

There are three parking options:

1) On-Street metered parking along Art Museum Drive
E-Z Park Meters accept coins, debit cards, and credit cards. After pre-paying, simply display the printed parking receipt on the dashboard of your vehicle. The rate is $0.50 per hour.

2) BMA-Gated Parking Lots
There is a flat parking rate of $5 from 5 p.m. until midnight.

3) JHU Homewood Campus (South Parking Garage and Metered Faculty Lots)
You may refer to http://www.parking.jhu.edu/general_maps.html, for visitor parking locations. There is a flat parking rate of $5 from 3:45 p.m. until midnight at the garage, and $2 per hour at the meters with a maximum charge of $5, valid until the end of the day.
