Unfortunately, due to the simplifications made in their formulations, ROMs can suffer from significantly reduced accuracy. One common simplifying assumption is the continuity of static or total pressure over vascular junctions. In many cases, this assumption has been shown to introduce significant error. We propose a model to account for this pressure difference, with the ulti","authors_text":"Alison L. Marsden, Eric F. Darve, Luca Pegolotti, Martin R. Pfaller, Natalia L.
