Speed comparison of single equation method based on saturated steam water spaces models

Simulators are extensively used as a tool for industrial training, design and development. The overall improvement in computational speed of simulator is very important and can be improved by redesigning the mathematical simulation models or by using faster computational platforms. Modern day simulators are using cloud computing platforms and other high performance computing systems. The complex algorithms employed in simulation of steam-water spaces and steam tables resulted in longer computational time. The use of cloud computing for simulation makes essential the optimization of cost of computing and cost of transmission. The quasi-numerical, quasi-steady state, Single Equation Method based saturated steam water space modeling can be employed to improve the speed of computation and to suit the new computing environments. This makes the simulator faster and cost effective. Experiments using differenet computing platforms show that the proposed single equation based quasi-numerical, quasi-steady state is around eight times faster than the steam-table iteration based modeling approach. © 2014, UK Simulation Society.
