BOSpulse 5.2 Improvement Of The Harmonic Solution Method

The harmonic flow solver that comes with BOSpulse has seen significant improvements regarding its accuracy, bringing it on par with the transient flow solver. As a consequence, you can speed up your pulsation analyses dramatically by switching from the transient solver to the harmonic solver.

The harmonic solver now involves a non-linear solution method that calculates a mean flow rate in such a way that the friction losses in the frequency domain are equivalent to the friction losses in the time domain. Consequently, the results calculated by the harmonic solver tend to differ only a few percent from the results calculated by the time transient solver.

Because the harmonic solver is much faster, it is now the default solver in API 618 and API 674 analyses. Naturally the transient solver is still available and will be fully supported in future releases.
