| Abstract: | The Basset force plays an important role in the momentum equations for relatively-small solid
particles moving close to a river bed. This force can make the numerical solution of these equations
computationally time- and memory-consuming. Reduction of the computational cost of the Basset
term is therefore strongly needed. In this paper, we present and discuss a two-stage methodology to
deal with the difficulties associated with the Basset force. First, we use an approximation of the
Basset term based on a semi-derivative (fractional mathematics); second, we redefine the integration
time of the term proposing the use of a number of previous jumps. Important savings in
computational time are reported. |
| Description: | Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization. |
