Hello everyone,
I am trying to model an electric boiler in simulink. Its a steady state process, so all the physical parameters are neglected and parameters such as volume and pressure remains constans. the equation which i have modelled is as follows
where
ρw = density of water
Vw = volume of water
m. = massflow rate of water
hs = enthalpy of steam
M = mass of metal
Cp = specific heat of metal
Tm = temperature of metal
Ts = temperature of saturated steam
n = number of tubes
D = Dia of tube
L = length of tube
∝ = heat transfer coefficient
When I run the equation I am getting a stepp rise in enthalpy with respect to time. I have attached the image of the equation and graph below. Please verify the equation and guide me through this.
