Improving broiler lifestyle: a CFD approach

Author: Humbert, U ; Wessels, GJC ; Smit, Jacoba E ; Ubbink, O Date: Jan 2014 Climate change poses environmental risks which can negatively affect livestock production. To circumvent this, it is possible to move livestock into environmentally controlled animal housings. In South Africa, this is practiced in the broiler ... Read more
Steady state CFD modelling of carbon dioxide release and methananogenesis in coal heaps

Author: Siyakatshana, Njabulo ; Ubbink, O ; Kekana, J ; Wessels, G Date: Jan 2011 The Kyoto Protocol and its related instruments have increased awareness of the phenomenon of global warming. The two main so-called greenhouse gases deemed to cause this effect have been identified as CO2 and CH4. Other greenhouse gases include ... Read more
Towards the development of a fully coupled arterial-venous 1D model: suitability of using a 1D finite volume method with staggered spatial discretization

Author: Bogaers, Alfred EJ ; De Villiers, AM ; Kok, S ; Ubbink, O ; Franz, T ; Reddy, BD ; Du Toit, CG Date: Jul 2012 In this paper we outline the development of a 1D finite volume model to solve for blood flow through the arterial system. The model is based on a staggered spatial discretization which leads to a stable solution scheme. This scheme can ... Read more
