The nature of the superfluid transition in porous glass has been confusing. Heat capacity measurements indicates scaling violations. Aerogel is a highly porous silica glass that we model by a diffusion limited cluster aggregation (DLCA) model. Superfluid He-4 in the aerogel pores is modeled by a 3DXY model. We determine scaling properties from Monte Carlo simulations. The results are comparable to experiments, and avoid scaling violations. Pictures show a DLCA cluster and heat capacity results.
