Abstract

We use observed frequencies of solar p-modes to test different formulations for calculating the convective flux. In particular, models using the usual mixing length theory and the formulation of Canuto and Mazzitelli for calculating the convective flux are compared to find that the latter yields frequencies that are closer to observed values. Inclusion of turbulent pressure is also found to improve the agreement with observed frequencies, but the magnitude of the difference is much smaller.
