A Test-Tube Condenser

Bond graph model of a vertical U-tube steam condenser coupled with a heat exchanger

A simulation model for a vertical U-tube steam condenser in which the condensate is stored at the bottom well is developed in this paper. The U-tubes carrying the coolant are partially submerged in the stored condensate and thus the bottom well acts as a heat exchanger. The storage of hydraulic and thermal energies is represented using a coupled pseudo-bond graph model. Advection effects are mo...

A Model of an Air-Conditioning Condenser and Evaporator with Emphasis on In-Tube Enhancement

A MODEL OF AN AIR-CONDITIONING CONDENSER AND EVAPORATOR WITH EMPHASIS ON IN-TUBE ENHANCEMENT Kuo-Hsiu Huang Michael B. Pate Mechanical Engineering Department Iowa state University Ames, Iowa 50011 A computational model for air-conditioning condensers and evaporators with in-tube enhancement has been developed. The purpose of this model is to provide a tool for the design of plate tinned-tube he...

Anti-Freezing Mechanism Analysis of a Finned Flat Tube in an Air-Cooled Condenser

In cold winter weather, the air-cooled condensers (ACCs) face serious freezing risks, especially with part load of the power generating unit. Therefore, it is of benefit to investigate the heat transfer process between the turbine exhaust steam and cooling air, by which the freezing mechanism of the finned tube bundles can be revealed. In this work, the flow and heat transfer models of the cool...

Test-Tube Baby

A test-tube baby [4] is the product of a successful human reproduction that results from methods beyond sexual intercourse [5] between a man and a woman and instead utilizes medical intervention that manipulates both the egg [6] and sperm [7] cells for successful fertilization [8]. The term was originally used to refer to the babies born from the earliest applications of artificial insemination...
