Question

Udf for variable velocity of bblood through an artery

Answer 1

Answer:

 · Human heart ejection is cyclically time-varying. Thus the velocity at the inlet of brachial artery is not set to be a constant, but instead with a time-varying periodic profile. Here we used cardiac cycle model and defined the UDF in Fluent. ... Figure 2 shows the flow velocity waveform at the inlet boundary
