Using mathematical tools from the theory of distributions one can provide an appropriate meaning of objects like eg. the delta function.</i></div><div style="margin: 0px; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue"; min-height: 15px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue";" class=""><b class="">Dominik Suwała</b></div><div style="margin: 0px; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue";" class=""><b class="">A tour on CFD algorithms: SIMPLE</b></div><div style="margin: 0px; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue"; min-height: 15px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue";" class=""><i class="">I this talk I will present one of the widely used computational fluid dynamics (CDF) algorithm: SIMPLE (Semi-Implicit Method for Pressure Linked Equations).
