Краткое описание

This study is dedicated to the cooling of Herschel-Bulkley fluids flowing in circular pipes. These fluids exhibit yield effect, their rheological comportment law being τ = τ_s+K·γⁿ and also some thermodependancy, the consistency being a function of the temperature according to K = a·exp−b_k·T. We present numerical results concerning the temporal development and also some experimental results for stationnary situations.
