We examine the properties of spiral shocks from a steady, adiabatic,

non-axisymmetric accretion disk around a compact star in binary. We first time

incorporate all the possible influences from binary through adopting the Roche

potential and Coriolis forces in the basic conservation equations. In this

paper, we assume the spiral shocks to be point-wise self-similar, and the flow

is in vertical hydrostatic equilibrium to simplify the study. We also

investigate the mass outflow due to the shock compression and apply it to the

accreting white dwarf in binary. We find that our model will be beneficial to

overcome the ad hoc assumption of optically thick wind generally used in the

studies of the progenitor of supernovae Ia.
