How to create a control loop simulation model to simulate the dynamic behavior of heat exchanger

A heat exchanger model will be created using DTDL. We want to simulate the dynamic behavior of this heat exchanger; for example, temperate control loop. But to my knowledge, DTDL cannot do the calculations so what are the simulation tools I can use for the simulation of the dynamic behavior of the heat exchanger.

Our workflow will be this; When we update or change the set point (temperature), the parameters (inlet steam flow rate, inlet steam temperature etc), from the DTDL will be used by the simulation tool and it will calculate the output (outlet temperature). Equations that represent the dynamic behavior of the heat exchanger will be in the simulation tool; like a transfer function and other parameters. Then this output gets updated to the twin. Our objective is to be able to represent the dynamic behavior of the digital twin so that AI can analyze the model and understand the whole process including the dynamic behavior.

    Hi HTMH

    If we can connect the temperature sensors or registers to IOT hub somehow (use ESP32 or Arudino as bridge to route data with MQTT/AMQP to IOT Hub )it can process or modified with Azure function to map the real time data in Digital twin.

    Diagram of IoT Hub device sending Temperature telemetry to a function in Azure, which updates a Temperature property on a twin in Azure Digital Twins.

    Diagram from the beginning of the article showing the full building scenario.

    Hope it helps.

    Thank you.
