Abstract We have numerically studied the coagulation and transportation of grains in the turbulent accretion solar nebula. Compared with the case of laminer nebula, the turbulence enhances the growth rate. The grains diffuse radially through the nebula owing to turbulent diffusion. The accreted interstellar grains form the reservoir, from which the new generations of grains grow. The opacity calculation shows that the initial thermal convection terminates earlier in the inner region and that there is a possibility of restart of the convection due to the accreted grains, particularly in the outer region. We discuss about the implications of our calculations to the evolution of the grain and nebula, and the formation of planetesimals.
