Parameters

k [-]: float

Nonlinear exponent

p_ref [Pa]: float

Reference pressure for which hold p(V_ref) = p_ref

V_ref [m 3]: float

Reference volume for which hold p(V_ref) = p_ref

Signals

V [m 3]: array

Volume enclosed by the Bag

p [Pa]: array

Pressure inside the Bag

Bag

The Bag module is introduced to simulate the effects of the pericardium on the heart. It applies an external pressure on the enclosed cavities. This pressure is dependent on the total volume of all cavities in the Bag, and is given by

(1)\[p(V) = p_{ref} \cdot \left({\frac{V}{V_{ref}}}\right)^k\]
