Three-Dimensional Attached Viscous Flow

Basic Principles and Theoretical Foundations

By: Ernst Heinrich Hirschel,Jean Cousteix,Wilhelm Kordulla

Viscous flow is treated usually in the frame of boundary-layer theory and as two-dimensional flow. Books on boundary layers give at most the describing equations for three-dimensional boundary layers, and solutions often only for some special cases. This book provides basic principles and theoretical foundations regarding three-dimensional attached viscous flow. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers. This wider scope is necessary in view of the theoretical and practical problems to be mastered in practice. The topics are weak, strong, and global interaction, the locality principle, properties of three-dimensional viscous flow, thermal surface effects, characteristic properties, wall compatibility conditions, connections between inviscid and viscous flow, flow topology, quasi-one- and two-dimensional flows, laminar-turbulent transition and turbulence. Though the primary flight speed range is that of civil air transport vehicles, flows past other flying vehicles up to hypersonic speeds are also considered. Emphasis is put on general three-dimensional attached viscous flows and not on three-dimensional boundary layers, as this wider scope is necessary in view of the theoretical and practical problems that have to be overcome in practice. The specific topics covered include weak, strong, and global interaction; the locality principle; properties of three-dimensional viscous flows; thermal surface effects; characteristic properties; wall compatibility conditions; connections between inviscid and viscous flows; flow topology; quasi-one- and two-dimensional flows; laminar-turbulent transition; and turbulence. Detailed discussions of examples illustrate these topics and the relevant phenomena encountered in three-dimensional viscous flows. The full governing equations, reference-temperature relations for qualitative considerations and estimations of flow properties, and coordinates for fuselages and wings are also provided. Sample problems with solutions allow readers to test their understanding.

The Sustainability of Hemp

An Overview of Product and Use in Business

By: Jonas Michael Wilhelm Westphal

The cannabis plant, as a hemp, could contribute better than previously thought to achieving the goals of the UN Sustainable Development Report, the so-called Agenda 2030 and its 17 SDGs (Sustainable Development Goals). From a health perspective, its medicinal use is the main focus, but it is also used in cosmetic products and in food offerings for humans and animals. In the context of the increasing climate crisis, hemp helps especially to cope with the CO2 problem: in agriculture by binding the CO2 similar to reforestation, in industry as a recyclable raw material substitute for example as a plastic substitute, in clothing, in technology or in construction. At the moment, unfortunately, the immense prices and high demand show a different picture, from citizens who want to but can't or aren't allowed to, from farmers who have to overcome immense bureaucratic hurdles to an industry that is deterred by complex rules and laws to invest. The essential shows how this potential could also be realized in Germany.
