“…3 shows the calculated Nu against Ra at various q. It is shown that Nu increases as Ra increases, which is similar to the results for two horizontal tubes [22]. This is because the convection in the enclosure will enhanced as Ra number increase.…”

“…In the last decade, many researchers have simulated the heat removal mechanism by means of natural convection in a heat exchanger containing several hot and cold pipes. Dai et al [2], Garoosi et al [3], Gap et al [4] and Wang et al [5] studied free convection heat transfer between hot and cold micro-tubes in a heat exchanger. Their results indicated that, the maximum heat transfer performance can be achieved when the hot tubes are located lower than the cold ones.…”

“…From energy saving point of view, improvement of heat transfer in any application of natural convection is a primary and crucial topic. Thus, several investigations can be found concentrating on natural convection [2][3][4][5][6][7]. Deng [2] studied laminar natural convection in a two dimensional square enclosure with two and three source-sink pairs on the vertical side walls.…”
