We have developed phenomenological turbulent effects with one-dimensional (1D) simulation based on Reynolds decomposition. Using the method, we have conducted a systematic study of 320 models changing progenitor mass, mixing-length parameter, and diffusion coefficients for internal energy, turbulent energy, and electron fraction. With employed turbulent effects, supernova explosion can be achieved even in 1D geometry.\u00a0\u00a01D+ can reproduce results of 2D simulation at a later phase after the core bounce.\u00a0\u00a0 \u00a0 The progenitor dependence of explodability Explosion energy ,PNS mass and so on are also investigated in the mixing-length parameter plane.\u00a0These simulations would help understand the role of turbulence in core-collapse supernovae.<\/p>\n","protected":false},"excerpt":{"rendered":"
