Table 7. Value or expression and description of reaction terms and parameters in current paper.

Terms Value or expression units Description
kapa Inline graphic (s−1) Platelets activation due to agonists; tct is the characteristic time, which can be used for adjusting the activation rate, and here we choose tct = 1s as provided Sorensen13,14; Inline graphic implies the reaction cannot be faster than platelets physical activation procedure and 99% platelets will be activated during the activation procedure if the agonists or shear stress is large enough tact is the characteristic time; tact is suggested to range from 0.1 s to 0.5 s considering the results by Frojmovic et al.69 and Richardson70.
Ω Inline graphic (N/A) aj refers to the concentration of ADP, TxA2 and Thrombin. Value of wj and aj,crit see Table 8
kspa Inline graphic (s−1) Platelet activation due to shear stress, τ. Expression tct,spa = 4.0 × 106τ−2.3 was provided by Goodman21 and Hellums71.
krpd Inline graphic (s−1) Unactivated platelets–deposited activated platelets ([RP]-[APd]), deposition rate. f refers to the face of a mesh cell and Inline graphic is the unit normal to the face. Details about how this term is calculated are provided in Supplemental Appendix.
kra 3.0 × 10−6 (m s−1) Constant related to krpd13,14.
kapd Inline graphic (s−1) Activated platelets-deposited activated platelets ([AP]-[APd]) deposition rate. Details about how this term is calculated are provided in Supplemental Appendix.
