Field Demonstration of Aviation Turbine Fuel MIL-T-83133C, Grade JP-8 (NATO Code F-34), at Fort Bliss, TX
1992Co-Authors: Walter E Butler, Ruben A. Alvarez, Douglas M. Yost, Steven R Westbrook, Janet P BuckinghamAbstract:Abstract : A JP-8 Fuel demonstration was initiated at Ft. Bliss, TX, to demonstrate the impact of using aviation turbine Fuel MIL-T-83133C, grade JP-8 in all military diesel Fuel-consuming ground vehicles and equipment. Three major organizations, one ordnance battalion and two activities with a total of 2807 vehicles/equipment (V/E), were identified as participants in the demonstration program, which is authorized to continue through 30 September 1991. No Fuel storage tank or V/E Fuel cells were drained and flushed prior to introduction of JP-8 Fuel. This procedure resulted in a commingling of JP-8 Fuel with existing diesel Fuel. As of 31 July 1990 approximately 4,700,000 gallons of JP-8 Fuel had been dispensed to user units at Ft. Bliss and at Ft. Irwin National Training Center (NTC) in California. Three areas of concern arose from the beginning of the program: (1) plugging of Fuel Filters, (2) loss of power, and (3) overheating. The use of JP-8 Fuel did not cause or exacerbate any V/E Fuel Filter plugging. Where power loss was apparent, generally it was commensurate with the difference in heating values between JP-8 and diesel Fuel. The V/E at Ft. Bliss operated satisfactorily with the JP-8 Fuel with no alterations, mechanical or otherwise, having to be made to any engines or Fuel systems. There were no major differences in Fuel procurement costs, V/E Fuel consumption, AOAP- directed oil changes, and Fuel-wetted component replacements.

A Comparative Study of Mixed Resolved–Unresolved CFD-DEM and Unresolved CFD-DEM Methods for the Solution of Particle-Laden Liquid Flows
Archives of Computational Methods in Engineering, 2019Co-Authors: Sahan Trushad Wickramasooriya Kuruneru, E. Sauret, Ewen Marechal, Florent Ravelet, Suvash Chandra Saha, Sofiane Khelladi, Michael Deligant, Yuantong GuAbstract:The exorbitant economic and environmental cost associated with fouling propels the need to develop advanced numerical methods to accurately decipher the underlying phenomena of fouling and multiphase fluid transport in jet-engine Fuel systems. Clogging of jet-Fuel systems results in the foulants to settle in seconds to form a porous layer which restricts Fuel flow. The objective of this research is to numerically examine the transient evolution of particle-laden liquid flow and particle accumulation on an idealized jet-Fuel Filter. This is achieved by using two numerical approaches: coupled unresolved computational fluid dynamics-discrete element method (CFD-DEM), and coupled mixed resolved–unresolved CFD-DEM method. We assess the efficacy of both numerical methods by comparing the numerical results against experimental data. Results have shown that the particle accumulation and deposition profiles are in good agreement with the experimental results. Moreover, it is found that the particle distribution spread along the length and height of the channel reflects the actual particle spread as observed in the experiments. The unresolved CFD-DEM and mixed resolved–resolved CFD-DEM method could be harnessed to study complex multiphase fluid flow transport in various other applications such as compact heat exchangers and fluidized beds.

Automotive Diesel Fuel Filter Qualification Methodology and Preliminary Screening Results
1992Co-Authors: Gary B Bessee, S.r. Westbrook, L. L. StavinohaAbstract:Abstract : This report covers a program to develop a methodology to evaluate military vehicle Fuel Filters that would become part of a proposed military Fuel Filter specification. For this program, thirteen different Fuel Filters used on military and commercial vehicles were tested using a multipass Fuel Filter test stand. Each Filter type was tested in triplicate. Test parameters measured included differential pressure across the Filter, particulate contamination in both the influent and effluent Fuel (measured gravimetrically), Filter load capacity, and Filter efficiency. The Filter test results varied widely. Analysis of the results illustrated the need for better specification and control of Filters used in Army Fuel systems. The Filtering media in some of the Filters tended to separate or allow channeling at widely varying pressure drops. Some of the higher efficiency Filters tested were also found to allow a significant number of large diameters particles to pass through.
