Experimental and numerical study on temperature field by freezing pipe of double chambers
In order to control the horizontal energy transfer of freezing pipe, a new type freezing pipe with two chambers was set up.The temperature field of this new freezing pipe was analyzed by model test and numerical simulation.The results show that the temperature field shape inside the 1.5 diameter of...

| description | In order to control the horizontal energy transfer of freezing pipe, a new type freezing pipe with two chambers was set up.The temperature field of this new freezing pipe was analyzed by model test and numerical simulation.The results show that the temperature field shape inside the 1.5 diameter of the new freezing pipe was U-shape and there was a remarkable temperature difference between the side of liquid nitrogen chamber and air chamber, which proved that the new freezing pipe would change the transfer of cool energy and have the effective capability of control freezing.On the other side, the temperature field shape outside the 1.5 diameter of the freezing pipe was circle-shape, which indicated the new freezing pipe had less effective efficiency on the control freezing when it is used in a large space.In conclusion，the new freezing pipe can control the freezing effectively during short time period, and can be used in municipal rescue engineering. |
