    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?

    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...

    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?

    Capacitive coupling clamp not working as expected

    I have one doubt regarding this, Will the power of burst effects anywhere in this process? Why I am asking is, the current is the rate of change of electrone's flow, so if we are coupling the burst with capacitive way we have to take care the no. of electrons that comes to the plate na? I know...

    Capacitive coupling clamp not working as expected

    I am first time working in this area, so I didn't understand source impedance of what you are asking. I have a chattering relay circuit, which can produce burst of upto 4KV and I am trying to connect the burst to the capacitive coupling clamp. But I am not seeing the burst coupled with the...

    What could be the ratings of inductor used?

    Can any one tell the power ratings of the components that can I use in the above circuit? I couldn't rectify the problem that present with the first stage(First MOSFET) of the circuit. The second and third stages (Second and third MOSFETs) are working fine, as I expected. I need to know how can...

    Capacitive coupling clamp not working as expected

    I just made a capacitive coupling clamp with aluminium. When I fed a burst signal of 500V, I could only see 6V across the plates. I have used 1.5mm thickness aluminium sheet. Why its not working as expected?

    What could be the ratings of inductor used?

    I have a circuit which can produce bursts of 500V. When I did this circuit, The 2.2 mH is burning. I want to know whether do we need to take care the power rating of inductor? After the test I tried the experiment without inductor too. I have used 2.2ohm, 1W resistor. That too started to burn...

    Low cost EFT generator design

    I am trying to make a EFT generator in low cost which can generate bursts specify by IEC61000-4-4. The circuit which I am working on is given as below. This is for making a high voltage of atleast 400V. I got this design from a paper. But it is not mentioned the values of R1 and R5. I am not...

    What is the meaning of 30W amplifier?

    This is the amplifier I am using. I was using it last few days, but it is not working nowadays. So I am looking for a new amplifier to buy which suits for my experiment. Is there any problem, if we have switched on the amplifier without load? I read some where, for class D we should not turn on...
