  1. On Turbulent Fluid Motion

    Burgers, J. M.
    The following report considers certain aspects of the statistical problems presented by turbulence. Attention has been given in the first place to correlations as defining a structure in the field and to their importance in the phenomenon of diffusion. In attempting to describe the structure of the field by resolving it into simple components, we are faced with the coupling between the components as expressed by the nonlinear form of the hydrodynamic equations of motion. A number of basic effects of nonlinearity in a dissipative system can be studied with the aid of a simplified mathematical model. This model enables...

  3. Water Tunnel Tests of the Hydrobomb

    Knapp, Robert T.; Doolittle, Harold L.
    This report covers Water Tunnel tests of a 2" diameter model of the hydrobomb, conducted at the Hydraulic Machinery Laboratory at the California Institute of Technology. This work was authorized by Dr. E. H. Colpitts, Chief of Section 6.1, NDRC, as a part of Project OD-99. The purpose of the tests was to determine the drag, cross force, moment, and center-of-pressure eccentricity for various settings of the vertical and horizontal rudders, and also the extent to which these rudders are effective in controlling the torpedo. Runs were also made to determine the cavitation effects produced under the specified operating conditions, namely,...

  4. Water Tunnel Tests of the MK13-1, MK13-2 and MK13-2A Torpedoes with Shroud Ring Tails

    Levy, Joseph
    The High Speed Water Tunnel is operated by the California Institute of Technology under Contract OEMsr-207 with the office of Scientific Research and Development and is sponsored by Division 6, Section 6.1 of the National Defense Research Committee. This report covers a series of preliminary water tunnel tests of a model of the Mk 13-1, 13-2, and 13-2A torpedoes with shroud ring tails added, and is a supplement to a previous report of this laboratory, entitled "Water Tunnel Tests of the Mk 1.3-1, Mk 13-2, and Mk 13-2A Torpedoes," file marked Section No. 6.1-sr-207-936, and dated November 9, 1943. In the course...

  5. Interview with Pol Duwez

    Duwez, Duwez P
    An interview in seven sessions, April 1979, with Pol Duwez, professor emeritus of applied physics in the Division of Engineering and Applied Science. Recollections of his childhood in Mons, Belgium, during the German occupation in World War I. Educated at the School of Mines in Mons and the University of Brussels, where Auguste Piccard was one of his professors. Comes to Caltech in 1933 as a research fellow, working with Theodore von Kármán and Fritz Zwicky on the plasticity of metallic crystals. Comments on interest of R. A. Millikan and Piccard on cosmic rays. Returns to Belgium, 1935, to become director...

  6. Interview with Ahmed Zewail

    Zewail, Ahmed
    Interview in seven sessions (June-November 2015) with Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics, and 1999 Nobel laureate in chemistry. Zewail talks at length about growing up on the banks of the Nile in Desouk, Egypt, describing family and cultural influences, and the interplay of education, politics, and faith during his youth and adolescence. He recalls his early “passion” for knowledge and fascination with science, and the moderate, “intellectually rich” Islam of his day. He talks about his studies at the University of Alexandria (BSc ’67, MSc ’69), the stimulating intellectual and socially tolerant environment there,...

  7. Interview with Gerald J. Wasserburg

    Wasserburg, Gerald J.
    An interview in four sessions, in April and May 1995, with Gerald J. Wasserburg, John D. MacArthur Professor of Geology and Geophysics, emeritus, in the Division of Geological and Planetary Sciences. After a stint in the U. S. Army, Dr. Wasserburg matriculated at Rutgers University, then the University of Chicago (BS 1951); graduate school at Chicago (MS 1952; PhD 1954). He joined the Caltech faculty as assistant professor of geology in 1955, becoming full professor in 1963 and MacArthur Professor in 1982. In this wide-ranging interview, he discusses growing up in New Jersey during the Depression, his early interest in...
