摘要：

We study vanishing viscosity solutions to the axisymmetric Euler equations without swirl with (relative) vorticity in L-p with p > 1. We show that these solutions satisfy the corresponding vorticity equations in the sense of renormalized solutions. Moreover, we show that the kinetic energy is preserved provided that p > 3/2 and the vorticity is nonnegative and has finite second moments.
