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. We find that smaller diffusive transport on the internal energy makes the…
