In this research, the combined displacement inside a closed square enclosure was investigated. The geometry of this chamber is considered as a quadrilateral with the same dimensions, which is tilted and the upper and lower sides are insulated, and the left side is hot and the right side is cold. The effect of changing the angle of the chamber wall in some specific angles (θ), changes in the volume ratio of nanoparticles in Reynolds numbers 10 and 100 and in Richardson numbers 0.1 and 1 in the range of laminar flow are investigated in two dimensions. The base fluid is water and the nanofluid mixture is considered homogeneous. To solve Navirastox and discrete energy equations, the equations were solved numerically. Discretized equations were solved by coding in Fortran software. The results are presented in the form of Nusselt number distribution, temperature contour, flow contour and velocity vector in different solutions. The results showed that increasing the volume fraction of nanoparticles in the base fluid increases the Reynolds number and the dimensionless Nusselt number. An increase in the Richardson number, especially at high Reynolds numbers, leads to a noticeable increase in the Nusselt number. Also, the highest amount of heat transfer is related to the angle of 90 degrees.
