Multiphase blood flow model

Introduction The modeling of blood flow is often carried out through numerical simulations, which require the incorporation of mathematical models based on fundamental principles of fluid mechanics. The multiphase blood flow model is an advanced computational technique that has been adopted to capture the dynamics of blood flow more accurately. This paper aims to provide an overview of the multiphase blood flow model and its applications in the field of biomedical engineering. Multiphase Blood Flow Model The multiphase blood flow model is a computational modeling technique that involves the simultaneous simulation of multiple phases of blood flow, such as plasma, red blood cells (RBCs), and platelets. The plasma is considered as the continuous phase, and the RBCs and platelets are modeled as the dispersed phases. The model can be classified into two primary categories, namely, the continuous method and the Lagrangian method. The continuous method is widely used in the medical industry and uses equations of conservation of mass, momentum, and energy to simulate blood flow. The simulation involves dividing the fluid domain into smaller control volumes, and the properties of each phase of the blood are determined according to the equations of motion. The continuity and momentum equations are then solved to determine the velocity and pressure field of the fluid domain. The Lagrangian method follows the motion of each particle of the dispersed phase within the continuous phase. This method is mostly used to simulate RBCs due to their complex deformations and shape variations. This method can predict the RBCs' pathline, stress, strain, and deformation history, which can provide significant insight into the biomechanical properties of blood. Applications of Multiphase Blood Flow Model The multiphase blood flow model has several applications in the field of biomedical engineering. The following are some of the significant applications: 1) Hemodynamics: The study of hemodynamics involves the study of blood flow and its impact on the cardiovascular system's diverse properties. The multiphase blood flow model can be used to simulate coronary artery blood flow to identify and diagnose coronary artery disease. 2) Drug delivery: The study of drug delivery involves the exploration of various dosage forms, mechanisms of drug absorption, and release profiles. The multiphase blood flow model can be used to simulate the transport and distribution of drugs in the bloodstream, enabling a more in-depth understanding of drug permeation and absorption. 3) Medical device engineering: The design of medical devices involves the optimization of design parameters to minimize the adverse effects on the body. The multiphase blood flow model can be used to simulate the flow of blood around medical devices such as stents, heart valves, and pacemakers to identify areas where clotting may occur. Conclusion The multiphase blood flow model has numerous applications in the field of biomedical engineering that are improving patient care and medical device design. It is an advanced computational technique that can accurately capture the complex dynamics of blood flow through the simultaneous modeling of multiple phases of blood flow. The multiphase blood flow model represents a significant step towards developing personalized medicine and continues to be a focus of research in biomedical engineering.
