Detroit—Keeping passengers cool in the 2001 PT Cruiser was a design challenge involving efficiency. The 2.4-liter four-cylinder engine taking up only 148.2 inch3 total volume necessitated designing a special air conditioning accumulator that would fit into a confined area.
The accumulator from Parker Hannifin Corp. (Lyon, NY) uses a patented helix design that improves oil circulation. "The helix design provides a swirling and stirring motion that helps keep the oil and refrigerant mixture consistent," says Cary Horamoto, engineering manager of Parker Hannifin's refrigeration and air conditioning division. Keeping the mixture consistent reduces the amount of oil needed for charging the system, creating a cost savings for DaimlerChrysler.
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.
