Preliminary design of radial turbomachines is supported by “single-channel” CFD models, ideal for design concepts comparison. Unfortunately, these models do not suit non-periodic domain calculations like those of turbines with vaneless spiral casings. A new approach that makes such domains periodic was implemented in the open-source code MULTALL and validated against non-periodic-domain results of state-of-the-art commercial codes.

Abstract
Preliminary design of radial turbomachines is supported by “single-channel” CFD models, ideal for design concepts comparison. Unfortunately, these models do not suit non-periodic domain calculations like those of turbines with vaneless spiral casings. A new approach that makes such domains periodic was implemented in the open-source code MULTALL and validated against non-periodic-domain results of state-of-the-art commercial codes.
