     thermoelectric (te) modules with annular geometry are very attractive for waste heat recovery within the automotive world, especially when integrated as stacks into tubular heat exchangers. the required temperature difference is built up between the coolant, which flows inside an inner tube, and the exhaust gas, which flows around an outer tube. the flow pattern of the exhaust gas can be axial or circumferential, which can lead to higher heat transfer coefficients on the outer surface of the tube. however, this multidimensional construction in combination with a complex flow pattern can lead to a nonuniform heat flux. additionally, the system experiences a nonuniform temperature distribution which consequently leads to complex conditions regarding the electrical potential. the relevant effects are investigated using a three-dimensional (3-d) numerical model implemented in the computational fluid dynamics (cfd) simulation environment star-ccm+. the model supports temperature-dependent characteristics of the materials, contact resistances, and parasitic effects in the te module. furthermore, it involves techniques to quickly find the exact maximum power point of the te module with the given boundary conditions. using the validated model the influence of the nonuniform temperature distribution is investigated with emphasis on the electrical output and te efficiency.
