    What is Conjugate Heat Transfer?

    CHT (Conjugate Heat Transfer) refers to situations in which multiple modes

    of heat transfer occur simultaneously.

    – Simultaneous multiple heat transfer modes occur in almost all real-world

    problems.

    – In some cases, certain heat transfer modes can be neglected.
