A numerical investigation was carried out on the effect of carbon nanotube (CNT)-water-nanofluid-filled Trombe wall on heat transfer and fluid flow inside a 3D typical room. Time depending governing equations are considered with applying hot temperature at the left surface (collector) of the Trombe wall. The left wall (glazing) of the room and a square part (window) at the right wall are considered at cold temperature. The effects of Rayleigh number and the nanofluid volume fractions and the Trombe wall height on the temperature field, flow structure and heat transfer rate, are studied. The results show that the addition of nanoparticles and the increase of the Trombe wall height, enhance the heat transfer considerably and affect the flow structure and the temperature field.
