MHMT is aimed to become one of the leading international annual congresses in the fields of momentum, heat and mass transfer. The congress is composed of 3 conferences. While each conference consists of an individual and separate theme, the 3 conferences share considerable overlap, which prompted the organization of this congress. ENFHT'20 - 5th International Conference on Experimental and Numerical Flow and Heat Transfer ICMFHT'20 - 5th International Conference on Multiphase Flow and Heat Transfer CSP'20 - 5th International Conference on Combustion Science and Process This congress will provide excellent opportunities to the scientists, researchers, industrial engineers, and university students to present their research achievements and to develop new collaborations and partnerships with experts in the field.
