Heat exchanger (double-pipe) (MF)#

The Heat exchanger (double-pipe) (MF) block models the process of heat exchange between two media separated by a wall.

Law of conservation of mass (1) :

(1)#\[\dot m_А+\dot m_В=0\]

where:

\(\dot m_A\) – mass flow rate at the input, [kg/s];

\(\dot m_В\) – mass flow rate at the outlet, [kg/s].

Law of conservation of energy (2) :

(2)#\[\phi_А + \phi_В+Q=0\]

where:

\(\phi_А\) – energy flow at the input, [W];

\(\phi_B\) – output energy flow, [W];

\(Q\) – heat flow through the wall, [W].

Number of Transfer Units (NTU) (3) :

(3)#\[NTU=\frac{UA}{C_{min}}\]

where:

\(UA\) – overall heat transfer coefficient, [W/K];

\(C_{min}\) – minimum heat capacity of the flow, [W/K].
