Automotive Aerodynamics

Automotive Aerodynamics Joseph Katz, San Diego State University, USA The automobile is an icon of modern technology because it includes most aspects of modern engineering, and it offers an exciting approach to engineering education. Of course there are many existing books on introductory fluid/aero dynamics but the majority of these are too long, focussed on aerospace and don’t adequately cover the basics. Therefore, there is room and a need for a concise, introductory textbook in this area. Automotive Aerodynamics fulfils this need and is an introductory textbook intended as a first course in the complex field of aero/fluid mechanics for engineering students. It introduces basic concepts and fluid properties, and covers fluid dynamic equations. Examples of automotive aerodynamics are included and the principles of computational fluid dynamics are introduced. This text also includes topics such as aeroacoustics and heat transfer which are important to engineering students and are closely related to the main topic of aero/fluid mechanics. This textbook contains complex mathematics, which not only serve as the foundation for future studies but also provide a road map for the present text. As the chapters evolve, focus is placed on more applicable examples, which can be solved in class using elementary algebra. The approach taken is designed to make the mathematics more approachable and easier to understand. Key features: • Concise textbook which provides an introduction to fluid mechanics and aerodynamics, with automotive applications • Written bya leading author in the field who has experience working with motor sports teams in industry • Explains basic concepts and equations before progressing to cover more advanced topics • Covers internal and external flows for automotive applications • Covers emerging areas of aeroacoustics and heat transfer Automotive Aerodynamics is a must-have textbook for undergraduate and graduate students in automotive and mechanical engineering, and is also a concise reference for engineers in industry.

Joseph Katz

Joseph Katz allegedly worked for Soviet intelligence from the 1930s to the late 1940s as one of its most active liaison agents. Katz was assigned management of the “First Line,” that part of the NKGB mission aimed at recruiting selected members of the Communist Party USA. He was an agent/group leader (gruppovik) and co-owner of a Soviet front company that manufactured gloves.

The Venona project suggests he may have been implicated, along with Amadeo Sabatini, in the murder of Walter Krivitsky in 1941. After the death of Jacob Golos in November 1943, spotting and recruitment was taken over by Katz by mid–1944, while Elizabeth Bentley continued as manager and courier. Katz was extremely active at this time. Katz was known to Elizabeth Bentley as “Jack.”

In 1944 Katz was put in charge of handling agent recruitments from the New York City TASS office headed by Vladimir Pravdin, former rezident of the NKGB in New York. And in September 1944 Katz was freed of other liaisons (operations) and was assigned to work directly under Washington D.C. Rezident Anatoli Gromov. Gromov came to the United States to implement a new security program of isolating agents from each other by a complicated arrangement of cutouts.

Katz and Bentley’s operations in New York and Washington were very extensive. Bentley would eventually name more than 80 individuals who were providing information to the Soviet intelligence from a dozen government institutions.

Katz informed Bentley at their first meeting in October 1944 that Gromov had been sent to the United States to improve security of NKGB operations. One aspect of this modernization was to have Bentley turn over to NKGB control all of her agents not previously surrendered to NKGB officers.

After Bentley's defection Katz was assigned the task of killing her, but the murder was never carried out. Katz moved to Western Europe to form a company for covering the illegal courier line between Europe and U.S. Katz lived in France from 1948 to 1951 then moved to Israel. His code names in the Venona project are "X" and "Informer".
