(TSI) Certified Thermal Systems Engineer (CTSE) Thermodynamic fundamentals?particularly the first and second laws?form the core of CTSE material, and you’ll need confidence working with entropy, enthalpy, and real gas behavior before test day. Heat transfer modes (conduction, convection, radiation), refrigeration cycles, and equipment sizing calculations appear heavily throughout. Strong algebra and calculus skills are non-negotiable; many questions require selecting the right formula and executing calculations under time pressure without reference materials.
