Gowrav New Member Gowrav Shenoy Join Date: Feb 2013 Posts: 22 Rep Power: 13	Hi all, I am trying heat transfer case for first time, i have taken a u tube in which water is hot flowing. Surrounding the tube created Box ( Air Volume) in which air flows at right angle,, i am able to get temperature drop for massflow in and pressure outlet condition. I am able to get nusselt no after the calculation on interfaces. But i am unable to set it in surface monitors there its showing constant value.. Can anyone explain what went wrong? Thanks
