The flow of fluids at branching junctions plays important kinematic and dynamic roles in most biological and industrial flow systems. The present paper highlights some key issues related to the flow of fluids at these junctions with special emphasis on the biological flow networks particularly blood transportation vasculature.

The proposed model incorporates more than one major nonlinearity corresponding to the fluid rheology and conduit mechanical properties, that is non-Newtonian effects and tube distensibility, and can be used to describe shear dependent flows of mainly viscous nature.

Predicting bifurcation angle effect on blood flow in the microvasculature.


Computation fluid dynamics (CFD) is a designing apparatus used to reenact the activity of thermoliquids in a framework. It is utilized by numerous businesses in their improvement work to dissect,

Fractal analysis of concurrently prepared latex rubber casts of the bronchial and vascular systems of the human lung

The data obtained here compellingly suggest that the design of the bronchial system, the pulmonary artery and the pulmonary vein of the human lung functionally comply with the Hess–Murray law or ‘the principle of minimum work’.

Mechanical perturbations trigger endothelial nitric oxide synthase activity in human red blood cells

The results of the study confirm that mechanical perturbations sensitize RBC-eNOS to produce NO, which ultimately defines physiological boundaries of RBC structure and functions, and propose that mild physical perturbation before, after, or during storage can improve viability of R BCs in blood banks.

Blood Vessel Branching: Beyond the Standard Calculus Problem

Summary Calculating the optimal angle for blood vessel branching is a standard calculus problem. However, optimality in that setting is judged by a cost functional that turns out not to give
