Design Considerations for Thin Liquid Film Wall Protection Systems S.I. Abdel-Khalik and M.Yoda Georgia Institute of Technology ARIES Project Meeting, UW-Madison September 19-20, 2001

2 OBJECTIVES lAssess feasibility of “attached” thin liquid film protection schemes for IFE systems lIdentify optimum design parameters & “parameter space windows” for reliable operation of such systems lEvaluate impact of wall protection scheme on other sub-systems operation

3 Primary Question #1 lCan we assure “full coverage” and “attachment” of film on cavity wall? — Do we have to?  Impact on geometry — flowing films on downward facing surfaces  Effect of beam ports  Fluid injection point(s)  Inherent instabilities (temperature gradients)

4 Primary Question #2 lCan the film really “protect” the first wall?  Solid wall response (thermal and mechanical) to microexplosions in the presence of an attached thin film  Shock wave strength  Direct energy deposition  Spectra of incident radiation  Wall material  Liquid film material & thickness

5 Primary Question #3 lCan the film “survive” between shots? Or does it have to be re-established after each shot?  Film response (thermal & hydrodynamic) to reflected light & X-rays  Film “condition” when ions arrive (ablation driven instability; mist formation)  Response of “disrupted” film to ions  Film response to “off-normal” events

6 Approach -- Methodology lUse HEIGHTS-IFE/SPLASH-IFE package (Hassanein — ANL)  Multi-layer structure (liquid film/solid wall)  Laser & X-ray deposition in composite structure  Up to ten ion debris species with various spectra  Detailed energy deposition & thermal response with phase change and vaporization  Liquid film stability (hydrodynamic & thermal)  Macroscopic erosion & splashing

7 Preliminary Question lWhat are the minimum film thickness & wetting rate (average film velocity) for a stable dry patch?  Isothermal film on a vertical adiabatic surface  Recent Model (El-Genk & Saber; 2001)  Earlier work by Hartely & Mugatroyd (1964); Hobler (1964); Bankoff (1971); Mikielewicz & Moszynski (1976); Doniec (1991)

10 Minimum Dimensionless Film Thickness  min Advancing Contact Angle Min. Dimensionless Film Thickness

11 Minimum Dimensionless Wetting Rate  min Advancing Contact Angle Min. Dimensionless Wetting Rate

12 Minimum Film Thickness  min & Average Velocity U: Lithium Contact Angle Min. Film Thickness (mm) Contact Angle Avg. Velocity (m/s)

13 Minimum Film Thickness & Average Velocity: Lithium-Lead Contact Angle Min. Film Thickness (mm) Contact Angle Avg. Velocity (m/s)

14 Minimum Film Thickness & Average Velocity: Flibe 66/34% Contact Angle Min. Film Thickness (mm) Contact Angle Avg. Velocity (m/s)

15 Conclusion lFor fluids of interest, a film thickness of ~ 1 mm and an average film velocity of ~ 1 m/s exceed the values required for a stable dry patch in isothermal films on vertical adiabatic surfaces. [Higher values ensure that the surface remains covered by a continuous thin liquid film]

16 The Path Forward lHydrodynamics of Thin Liquid films  Surface orientation (downward facing)  Chamber geometry (injection locations; beam ports protection) lResponse of liquid film/solid wall system to microexplosions  Thermal & hydrodynamic response of liquid  Thermal & mechanical response of wall
