The first mode (Flow 1) was produced by placing the pouring cup over the downsprue and incorporating a pressed ceramic filter between Ref 2 and Ref 3.
Due to no regulation effect, such as the ceramic filter could cause in the previous filling, the front surface of the liquid is more extended even during the ascending part of the flow when the average flow velocity is 55 cm*sec -1, slightly over the critical value mentioned in the literature.
