In this paper, an analysis of three-dimensional squeezing flow of carbon nanotubes (CNTs) based nanofluids in a rotating channel with a permeable fixed bottom wall by taking into account the effect of thermal radiation has been presented. The partial differential equations (PDEs) governing the problem were converted to ODEs and then solved using numerical method. The effects of changes in the values of various parameters on linear and an- gular velocity, temperature, skin friction coefficient, and local Nusselt number profiles have been investigated and for various nanofluids composed of SWCNT and MWCNT as nanoparticles and ethylene glycol as the base fluid. The most important results obtained from these figures are the oscillating behavior of the horizontal linear velocity profile due to the changes in the rotation parameter, the reverse flow in the central areas of the channel, the reduction of the temperature profile caused by increasing the radiation parameter, the direct relationship be- tween the Eckert number and the heat transfer rate in the upper channel wall, and their reverse relationship in the lower wall of the channel.
