Convective Heat Transfer from Realistic Ice Accretion Roughness

Ice accretion effects are mitigated during aircraft design using computer codes such as LEWICE. The characterization of convective heat transfer from surfaces with ice roughness is a significant area for improvement of these codes. Funded through NASA Collaborative Agreement No. NNX12AB85A, the current effort focuses on the measurement of convective heat transfer to flows over surfaces with realistic ice roughness properties. The project consists of three primary tasks: 1) measuring the convective enhancement of constant freestream velocity flows over surfaces with realistic ice roughness, 2) measuring the convection heat transfer of flows interacting with the leading edge of an aircraft wing with realistic ice roughness, and 3) measuring the convective enhancement of stagnating flows over surfaces with realistic ice roughness.  The project efforts are supported by collaborative activities at the Icing Research Branch at NASA Glenn to measure ice roughness exhibited by airfoils experiencing short-duration icing events. Secondary efforts of the project involve the evaluation of ice roughness properties from three-dimensional laser scans of iced airfoil surfaces created in the Icing Research Tunnel at NASA Glenn. The ultimate goal of the effort is to implement new correlations or advanced approaches for predicting convective heat transfer from realistic ice roughness distributions in current and future ice accretion codes. The first two images below demonstrate the difference between the relative roughness measured using a laser scan of an iced airfoil compared to the ice thickness or height relative to the clean airfoil surface. The third image below shows measurements of convective heat transfer rates along a surface exhibiting scaled ice accretion roughness statistical properties and a smooth-to-rough transition.

Biomimetic Hair Sensor Arrays for Aircraft Gust Mitigation

Bats and many species of insects use arrays of hairs or antennae to detect atmospheric gusts and mitigate their effects on their flight paths. Small military air vehicles to be used in future battlefield situations will also be susceptible to atmospheric gusts. Arrays of biomimetic hair sensor are being explored to help small air vehicles mitigate the adverse effects of atmospheric gusts on craft guidance and control. Research efforts are underway at Baylor to characterize the fluid-structure interaction of surface mounted carbon fiber “hairs” with unsteady flows representative of atmospheric gusts. While the carbon fibers are passive in that they do not produce an electrical signal that could be used for aircraft guidance or control, the measurements and resulting mathematical models will be used to design and fine tune sensors for detecting various types of unsteady flow phenomena affecting small air vehicles. The work is being performed in collaboration with engineers in the Air Force Research Laboratory, Munitions Directorate at Eglin Air Force Base. The image below is from a video reporting the results of image analysis measurements of the deflection of a passive hair in unsteady flows. The time tracking chart of tip displacement versus time in the image demonstrates four significant events during the unsteady flow tests: 1) the wind-tunnel flow speed ramp-up to 9 m/s (which occurs essentially linearly at 1 m/s per second), 2) a series of three discrete flap pulses, 3) two sinusoidal flap actuations with the amplitude of the second actuation being larger than the first, and 4) a second series of three discrete flap pulses where the first discrete pulse was very large.

Shapshot!

Flows Over Rough Surfaces

Following the work of Dr. B. K. Hodge (Mississippi State University), Dr. R. P. Taylor (Mississippi State University), Dr. H. W. Coleman (University of Alabama-Huntsville), and M. H. Hosni (Kansas State University), Dr. McClain has continued development of the well-known discrete element model for the computation of the interaction of surface roughness with turbulent flow and convective heat transfer.  Dr. McClain's research has extended the discrete-element model to include randomly-rough surfaces such as those found on high-usage gas turbine blades.  This research was supported by the U.S. Department of Energy, National Energy Technology Laboratory, and the South Carolina Institute for Energy Studies and was performed in collaboration with Maj. J. P. Bons, Dr. R. Sondergaard, and Dr. R. Rivir at the Air Force Research Laboratory.

Personal Vehicle Fuel Economy

As part of Alabama Department of Economic and Community Affairs (ADECA) Grant No. 1EX SEP06 10, "Consumer Practices for Maximizing Fuel Economy," a fuel consumption simulator (UABFCS) was developed to help students in Driver's Education courses identify driving practices that maximize a vehicle's fuel economy. UABFCS was developed as a first-person driving simulation and resembles the video-game driving simulators that are available for recreation. While the simulator was created for use with inexpensive off-the-shelf equipment, the simulator uses an incompressible flow model of the intake and exhaust processes with realistic transmission and torque converter models to predict fuel consumption and vehicle performance. The engine and transmission models are calibrated using manufacturer reported engine performance data. The resulting simulator operates quickly enough to provide visual continuity and captures the performance of a mid-sized sedan with a five-speed automatic transmission.  A brochure, a teaching manual, and a supporting website were also developed as fuel economy resources for Alabama drivers.
