A computational study has been performed to see the effects of electro-thermo-convection induced via a strong unipolar injection between two concentric or eccentric cylinders using the finite volume method. The parameters are taken in the range of radius ratio 0.1 ≤ Г ≤ 0.9, injection strength in the range of 1 ≤ C ≤ 20, mobility number changes in the range 4 ≤ M ≤ 150, electric Rayleigh number in the range of 100 ≤ T ≤ 800, and Rayleigh number changes in the range of 5000 ≤ Ra ≤ 25000. It is observed that the most important effective parameter is radius ratio, which affects both heat and fluid flow. Moreover, electrical Rayleigh numbers suppress the thermo-convection and in any case higher transfer is observed due to electric charge injection.
