Dr. Tatom, a registered professional engineer, has a broad engineering background with over 39 years experience in turbulent fluid dynamics. He has pioneered research in predicting turbulence properties in a flow field based on mean flow properties. In the field of turbulent fluid dynamics he has served as a consultant to a number of government agencies including: the Army Ballistic Missile Defense Systems Command; the National Aeronautics and Space Administration; the National Oceanic and Atmospheric Administration; the Tennessee Valley Authority; the U.S. Army Corps of Engineers; the U.S. Army Engineer Waterways Experiment Station; the Department of Energy; the Department of Labor; and the Occupational Safety and Health Administration. He has also served as a consultant to a number of private organizations including: the Gas Research Institute; Massachusetts Institute of Technology; Arthur D. Little, Inc.; Northrop Corporation; and General Dynamics Corporation. In 1983, he received NASA's New Technology Award for his work in the simulation of atmospheric turbulence.
Dr. Tatom has extensive experience in explosive damage assessment. He was involved in the Company-funded study dealing with the Nuclear Damage Assessment Model (NDAM), and subsequently participated in the development of the Enhanced Nuclear Damage Assessment Model (ENDAM) and the High Explosive Damage Assessment Model (HEXDAM). He conducted a study for the Southwest Research Institute (SRI) which involved verifying the HEXD AM damage algorithm and correlating the damage predictions generated by HEXDAM with the SRI pressure-impulse diagrams. He is the author of the Vulnerability Assessment of Structurally Damaging Impulses and Pressures (VASDIP) concept and the Vapor Cloud Explosion Damage Assessment Model (VEXDAM). Most recently, he developed the HEXDAM Man and VEXDAM Man concepts .
Dr. Tatom's interest in tornadoes results from his experience with five such storms which have passed near his home in 1967 (F2), 1974 (F5), 1976 (F2), 1989 (F4), and 1995 (F4). He holds a copyright on the Site Analysis of Tornado Threat (SATT) software. His research with predicting pressure fluctuations on the surface of an aerospace vehicle, under a NASA SBIR program, served as the basis for his originating the idea of the seismic detection of tornadoes.
Dr. Tatom is the originator of both the TURBAN and SURPRESS programs. In addition, he has been involved in government-funded studies dealing with phenomenological turbulence models and statistical turbulence simulation for the past 26 years. Such studies dealing with turbulence simulation served as the motivating factor for his original research in the field of fractional calculus during the last 20 years. In this regard, he has developed the basic relationship between fractional calculus and fractals.
Dr. Tatom currently holds the position of President and Chief Engineer of EAI. His prior industrial experience includes employment by Science Applications, Inc. (Chief Scientist Huntsville Division), Texas Instruments, Inc. (Member of the Technical Staff), Northrop Corporation (Chief of Aero-thermodynamics Branch), and DuPont (Process Engineer). Dr. Tatom has served in the past at the University of Alabama in Huntsville, Auburn University, and Georgia Institute of Technology. In addition he has served as a guest lecturer on turbulence models at the Naval Surface Weapons Center. Dr. Tatom is a member of Sigma Xi, National Society of Professional Engineers, and Society of Explosive Engineers.
Recently, Dr. Tatom has ventured well outside of his formal field of training and has proposed a new physical model for gravitational effects, based on the temporal inertia of matter.
