The complex unsteady airflow characteristics of certain aircraft features, such as landing gears and weapon bays, produce pressure fluctuations that reach unacceptable levels for operation and safety at transonic speeds.
By using the same technique that recently revealed two planets more than 5,000 light years away from Earth, Ohio State University researchers could again potentially uncover new celestial bodies.
In a lush valley on the border of Switzerland and France, more than 1,000 physicists, engineers, and technicians from 30 countries are working to answer questions about the fundamental nature of matter.
Scientists are developing hypersonic aircraft that can travel at speeds beyond Mach 5 (3,800 mph) and travel from New York to London in less than an hour. In military applications, flight above Mach 8 will be needed for effective homeland security. Several technical obstacles remain, however.
The ALICE experiment, short for A Large Ion Collider Experiment, is a massive effort to study the birth of matter involving a collaboration of more than 1,000 physicists, engineers, and technicians from 30 countries. The Ohio Supercomputer Center serves as a key resource for hosting data and analysis codes in North America.
Aerospace engineers such as Ohio State University professor Jen-Ping Chen, Ph.D., depend on modeling and simulations of turbomachinery, the alternating sections of spinning and fixed blades in a jet engine’s compressor and turbine, because the multiple stages and extreme temperatures make it difficult to conduct experimental measurements.
