Mechanical Solutions, Inc. (MSI) provides new equipment design, computer-aided analysis, installed equipment field testing and problem solutions. MSI staff performs these tasks for all types of Pumps, Compressors, Fans, Turbines, and Motors. For pumps and compressors, expertise includes both centrifugal and positive displacement (e.g. reciprocating or screw) configurations. Turbine knowledge and experience include hydraulic turbine generators (“hydroturbines”) as well as aircraft gas turbine engines and land-based gas or steam turbine power generation systems. Applications include green energy, power, process, petrochemical, paper, and water resource industries.
MSI uses advanced finite element analysis (FEA), rotordynamics, and torsional analysis tools, and uses computational fluid dynamics (CFD) to analyze 3-D steady or unsteady fluid flows and heat transfer, enabled by its 230 high speed processor supercomputer. MSI also uses top-of-the-line testing equipment, including multichannel FFT analyzers (up to 200 simultaneous channels) to accurately read the outputs of various vibration, stress/strain, and pressure sensors, as a function of both time and frequency. As a unique additional test capability, MSI uses motion magnification video cameras to amplify and display scene vibration by 1000x. MSI uses calibrated exciters while equipment remains running, to locate structural, rotor, and acoustic natural frequency resonances as they exist at any particular operating point, without interfering with machinery operation. In addition, MSI performs stress, acoustic, dynamic pressure pulsation, electric current spectrum, and aero/hydraulic performance testing.
MSI also has been project team leader in the development of advanced rocket turbopumps, as well as turbopump diagnostics, for the U.S. Air Force and NASA Marshall Space Flight Center. MSI is funded for several large projects with the U.S. Navy and Air Force involving vision-based systems that automatically evaluate and display/amplify machinery or system dynamic events. As a result of these projects, MSI has developed its VibVue® vibration motion magnification system, which can magnify vibration 1000x in the full field-of-view of the equipment. This system is available as a service, or for purchase.
Mechanical Solutions has a staff of approximately 30 technical professionals, many of whom are well known internationally in the area of pumps, compressors, and turbines. For example, MSI’s Dr. Edward Bennett won the ASME Gopalakrishnan award for best pump fluids technologist, and was later awarded another ASME medal for CFD. MSI’s Paul Boyadjis has won the Hydraulic Institute 2021 Standards Partner of the Year award. Since its founding in 1996, MSI has strived to provide best-in-class service throughout the world.
William D. Marscher has over 50 years of experience in the field of Fluid Systems and their rotating and reciprocating machinery, particularly large turbines, generators, compressors, and pumps. His typical work responsibilities include design, analysis, and testing of all types of plant machinery, as well as other types of fluid and mechanical systems.
Mr. Marscher received a B.S.M.E. from Cornell University in 1970, and a Master Eng. (Mech. Des.) in 1972, when he was a NASA Fellow and the lead graduate student for the original Mars Rover Design project. In 1976, he received an M.Sc. in Engineering Physics from Rensselaer Polytechnic Institute. He is a registered and licensed Professional Engineer, State of New Jersey Lic. No. 40626.
For 25 years, Mr. Marscher has been one of the U.S. voting representatives on the ISO (International Standards Organization) TC108 committee, and has been the US Coordinator concerning, among other issues, machinery dynamics of centrifugal pumps and hydraulic turbine generators. He is past president of the Society of Tribologists & Lubrication Engineers (STLE), the primary technical society worldwide for the study and design of bearings, seals, wear, and erosion issues in machinery. For the past 45 years he has been a voting member of the ASTM Fatigue Standards Committee E9, as well as the ASTM Wear & Erosion Standards Committee G2. He is also the past Board of Directors Chairman for the Machinery Failure Prevention Technology Society (MFPT), and has been active in the Vibration Institute. Mr. Marscher is a 23-year member of the Texas A&M Turbine-Pump Users Symposium Advisory Committee (essentially the Board of Directors for the Symposium). For ASME, Mr. Marscher was Chair of the Predictive Maintenance committee, and was Organizing and Presiding Chair of the 1993 RoCon Rotating Machinery Conference and the 1995 Tribology Conference.
Mr. Marscher has written thirteen handbook chapters for various major engineering handbooks, which have focused on turbomachinery mechanical issues, including dynamics, and bearing and seal design In previous employ, he was a senior engineer Pratt & Whitney Aircraft Engines, and Director of Mechanical Engineering for Worthington HQ (pumps, compressors, and turbines), and for Dresser Worthington Division after their acquisition of Worthington. Later, he was VP of Concepts NREC, from which 30 years ago he spun off Mechanical Solutions, Inc. as an independent turbomachinery technology company. He has since become a charter Standards Partner for the Hydraulic Institute (HI), the trade association for the pump industry, became Vice Chair of the vibration technical committee for HI, and was HI Standards Partner of the Year for 2018. He also won the 2019 Vibration Institute MFPT Frarey Award for Diagnostics Excellence.
