Wind energy is clearly a hot topic today—and growing in importance. Bearing giant SKF, which works closely with wind turbine manufacturers to supply main bearings, and bearings for the transmission, generators, and blade pitch systems, says that its sales to the industry have doubled in 2001. In fact, wind energy could supply up to 20% of U.S. energy needs, says the American Wind Energy Association.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
