Then the thermal analysis is performed on cylinder head, coated with 3Al2O3 .2SiO2 (mullite) (Al2O3= 60%, SiO2= 40%) material by means of using a commercial code, namely ANSYS. Finally, the temperature distributions are compared with each other. Heat transfer models have been developed for cylinder head with and without thermal insulation coating, which is incorporated in the simulated program. Gas wall heat transfer calculations are based on Annand's heat transfer model for IC engines. The effect of coating on the thermal behavior of the cylinder head is investigated using finite element analysis.

It observed that the heat transfer in the helical coil tube is higher as compared to the straight tube due to their shape. Inclined helical coil tube heat exchanger offers advantageous over straight tubes due to their compactness and increased heat transfer coefficient. The increased heat transfer coefficients are a consequence of the curvature of the coil, which induces centrifugal forces to act on the moving syngas. Due to the curvature effect, the fluid streams in the outer side of the pipe moves faster than the syngas streams on the inner side of the tube. Heat transfer augmentation techniques refer to various methods used to increase the heat transfer rate without changing much the overall performance of the system. The arrangements are useful in a variety of applications where more heat transfer rates ...
