Farklı kalp atım hızlarının (HR50–HR110) aortik hemodinamik parametreler üzerindeki etkileri, hesaplamalı akışkanlar dinamiği (CFD) yöntemiyle incelenmiştir. Sayısal analizlerde aort duvarı rijit kabul edilerek, tek yönlü akış çözümlemesi gerçekleştirilmiştir. Brakiyosefalik, sol ortak karotis, sol subklavyen ve abdominal aort çıkışlarında elde edilen hız profilleri ile duvar üzerindeki basınç ve duvar kayma gerilimi (WSS) dağılımları, zamana bağlı olarak karşılaştırılmıştır. Kalp atım hızının artışıyla birlikte çıkış hızlarında ve duvar üzerindeki mekanik yüklerde belirgin değişimler gözlemlenmiş; yüksek HR koşullarında daha erken ve daha yüksek tepe değerlerine ulaşılmıştır. Dalga yayılımı ve geri yansıma etkilerinin, özellikle sistol sonrası dönemde basınç ve WSS eğrileri üzerinde farklı zamanlamalarla ortaya çıktığı belirlenmiştir. Elde edilen bulgular, HR değişiminin aortik sistemdeki akış rejimi ve duvar mekaniği üzerinde doğrudan etkili olduğunu ortaya koymakta; rijit duvar modellemesinin temel dalga mekaniği analizleri açısından işlevsel bir yöntem sunduğunu göstermektedir.

NUMERICAL ANALYSIS OF THE EFFECTS OF DIFFERENT HEART RATES ON BLOOD FLOW DYNAMICS IN THE AORTIC VESSEL
Öz
The effects of varying heart rates (HR50–HR110) on aortic hemodynamic parameters were investigated using computational fluid dynamics (CFD) methods. A rigid wall assumption was employed in the simulations, and one-way flow analyses were carried out. Time-dependent velocity profiles at the outlets of the brachiocephalic, left common carotid, left subclavian, and abdominal aorta were evaluated along with corresponding pressure and wall shear stress (WSS) distributions. Increasing heart rate resulted in noticeable changes in both outlet flow characteristics and mechanical loading on the vessel wall, with earlier and higher peak values observed under elevated HR conditions. Wave propagation and reflection effects became more pronounced during the post-systolic phase, leading to temporal shifts in both pressure and WSS profiles. These findings highlight the direct influence of heart rate variability on flow dynamics and wall mechanics and underline the utility of rigid wall modeling for investigating fundamental wave phenomena
