Available in PDF, EPUB and Kindle. Book excerpt: An experimental and analytical study of laminar, free-convective combustion of a liquid metal from a wick was performed, using lithium and sulfur hexafluoride as the reactant combination. Observations of the combustion process indicate a vapor-phase reaction with products condensing on the fuel surface and in the vapor phase, but not in the flame. Data were obtained for the lithium burning rate in sulfur hexafluoride as a function of: wick length, ambient pressure, and concentration of inert diluent in the ambient gas. Data were also obtained for the relationship between wick surface temperature and ambient pressure. Two theoretical models using a film-theory approximation were developed. The effect of natural convection shown by the variation of burning rate with wick length is well described by the approach developed by Spalding.

Book excerpt: A numerical study is conducted to study lithium-sulfur hexafluoride (Li-SF6) wick diffusion flames. The objective of this study is to assess the effects of changing the geometry (height H and aspect ratio H/yo) and ambient conditions (free-stream velocity u infinity and gravity) on the burning rate and heat transfer. Wick combustion is identified as a boundary-layer gaseous diffusion flame with multiphase combustion products. A mathematical model for wick diffusion flames is established employing a conserved scalar approach. Both forced and mixed convective burning conditions are considered. Laminar, variable-property, boundary-layer equations are cast into dimensionless forms using the modified Howarth-Dorodnitzyn transformation for vertical plates and cylinders. The state relationships for the properties are taken from existing data of Li-SF6 combustion at a pressure of P = 0.01 MPa. Forced convective burning, for which the Reynolds number (Re = u infinity H/v infinity) is the important dimensionless parameter, is studied first. The results show that increasing u infinity increases the total burning rate, m. A relationship between m and Re and Re is obtained for both planar and cylindrical wicks of a given geometry (H = 100 mm, yo = 12.5 mm). The flatplate solution yields a fuel mass burning rate per unit surface area (i.e. local fuel burning rate) following the x-1/2 dependence of the classical similarity solution, where x is the streamwise distance. This dependence is not evident in the cylinder solution. Cylindrical wick geometries yield enhanced burning rates over planar wicks.
