✦ Synopsis

Calculations have been performed to determine the effect of the scattering distribution on radiation transfer in an absorbing-scattering liquid which is irradiated across an air interface. The scattering distribution has been systematically varied by changing lhe asymmetry factor used in the Henyey-Greenslein form of the phase function, and calculations have been based on the discrete ordinate, forward scattering and three-flux methods of solving the equation of transfer. A change in the scattering distribution from one which is highly peaked in the forward direction to one which is isotropic has the effect of increasing radiation absorption in the surface layers of the liquid, as well as the overall reflectance of the liquid. The three-flux predictions agree well with those of the discrete ordinate method over a wide range of scattering distributions, while there is poor agreement between the discrete ordinate and forward scattering results.
