Influences of dispersing hybrid nanoparticles and imposing permeable media on cooling performance of tube have been demonstrated in this investigation. The behavior of system with reporting entropy generation has been analyzed. To grow the rotational flow, turbulator within the test section has been mounted and pip experiences constant heat flux in this section. For simulating three dimensional laminar steady flow, finite volume method was operated and for applying porous terms, UDF according to Darcy model has been applied to enforce the source terms. Comparing the outputs with previous article proves the existence of good accommodation. Dispersing hybrid nano-powders, not only enhance the cooling rate but also decrease the total irreversibility of system. The heating term of S
gen
is much greater than other components and it decreases about 7.72% when Da = 10, Re = 1e2. As Da goes up, the heating term augments around 8.11% while the frictional term declines around 28.34%. As speed of inlet augments, the amount of S
gen,th
declines around 19%.
