Performance Simulation of Mining Screw Compressor

摘要：

On the analysis of pressure pulsation simulation of the pressing chamber, the mathematic model of numerical calculation error in its discharging stage was developed based on the Simpson formula of error criterion, which was contributed to settle the calculation divergence involved from the accumulation of the calculation rounding-off error by Rouge-Kutta method. Meanwhile, By mathematic deducing, the stability criterion of numerical calculation of pressure pulsation simulation in discharging stage was put forwarded, which was beneficial to the convergence of the results of the simulation calculation.
