    Model developed from performance curves are dynamic models?

    My end objective is to make complete simulink model for rotory air compressor. So this heat exchanger will become one of the subsystem in my model. Can you tell me, if I am using a heat exchanger modeled with this approach can mimic the actual system functionality?

    Model developed from performance curves are dynamic models?

    Do you think, is it because the test data gives the details of only at steady state ?

    Model developed from performance curves are dynamic models?

    I am trying to model a real heat exchanger in simulink. I dont have the geometry data. But I have UA curve with me. If I have developed the model with UA curve, will it be dynamic in nature?

    MATLAB How can I run Python by getting values from Matlab

    I have a python script for which the input data are coming from Matlab. I have tried to use pymatlab, but it is failing. Can anyone suggest any other method?

    Dynamic modeling of a system and transients of the system

    Can anybody help to derive a mathematical model of an air storage tank for an air compressor system? I have a scew type compressor(fixed speed type), which will deliver 1000cfm to a storage tank. The output for end use require 80-90psi. But the load(air flow output from tank) is varying w.r.t...

    Dynamic modeling of a system and transients of the system

    I mean differential equation w.r.t time only. I have an idea, what is transient behaviour is.

    Dynamic modeling of a system and transients of the system

    That means, if the system modelled with differential equations will includes the transients. Isn't it?

    Dynamic modeling of a system and transients of the system

    Consider, I have a dynamic system model for air compressor. Which means I have modelled the system by including its physics. Does this means I also included the transients of the system? What I think is, when i modelled any system with equations, I think that includes the transients. Is it...

    How to choose automatic voltage levels from a battery

    Hi.. I have a 40 volt (2.5Ah) , Lithium Ion battery. I need to use this battery for 20V application as well as 40V application. How to make an automatic voltage level chooser module for respective application?

    What could be the ratings of inductor used?

    Can Anybody tell why the current from the source(12V Voltage source) goes negative side?

    What could be the ratings of inductor used?

    Now I have done the same circuit in copper pcb, with soldering. But I am using signal generator to give the switching pulses to the MOSFET and I am using DC power supply for giving 12V Vcc. So will there be issue with ground? Does the circuit needs pull-down resistors ?

    What could be the ratings of inductor used?

    I am checking the first part of the circuit. I have a toroidal Inductor which can pass upto 3.4Amps. Now the inductor working fine, but nothing seeing at output. Is that because, the resistors and capacitors used are of higher power ratings?
