**Heat transfer** ================= Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. .. py:currentmodule:: symplyphysics.laws.thermodynamics.heat_transfer **Contents:** .. toctree:: :maxdepth: 4 laws.thermodynamics.heat_transfer.equation_in_homogeneous_medium_in_one_dimension laws.thermodynamics.heat_transfer.general_equation_in_one_dimension laws.thermodynamics.heat_transfer.solution_with_zero_temperature_boundaries
