Abstract: A vehicular exhaust pipe structure includes an outer pipe extending along a front-rear direction of a vehicle and an inner pipe disposed inside the outer pipe along an axial direction of the outer pipe. The inner pipe is joined to the outer pipe such that a vacuum layer is formed between the inner pipe and the outer pipe. The inner pipe includes a pseudo-cylindrical concave polyhedral shell-shaped part.

Abstract: A hydroform tube includes a first end and a second end. The hydroform tube includes a plurality of sides including a first side and a second side, and a fillet extending from the first side to the second side. The first side, the second side, and the fillet extend from the first end to the second end. The plurality of sides form different shapes at two cross-sections between the first end and the second end. The tube has substantially the same perimeter P at all cross-sections from the first end to the second end. The fillet has a radius R. The radius R is defined by a same formula at all cross-sections from the first end to the second end.

Abstract: The present invention provides a transfer line exchanger which is optimized for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The transfer line exchanger is designed by computer modeling a transfer line exchanger in which the cross section of flow path is substantially circular and modeling the operation of the transfer line under industrial conditions to validate the model design and its operation. Then iteratively the model design is deformed and the operation of the deformed part is modeled and compared to values obtained with other deformed models until the value of the objective function is optimized (e.g. at an extreme) or the change in the objective function is approaching zero.
