Melting Stage Analysis for Indirect Freeze Desalination

Creator:: Pratt, Mason G.
Abstract:: To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, ﬁrst, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The ﬁrst...

Preliminary Numerical Study of a Condenser Using Fractal-Like Patterned Hydrophobic and Hydrophilic Strips

Creator:: Lazaroff, Spencer A.
Abstract:: Condensers are vital components of power plants and are often one of the most major cost concerns when planning construction. Generally speaking, the surface area required to dissipate the heat generated in the boiler is so great that enormous and expensive structures are necessary. The usage of a hybrid surface...

Evaluation of the predictive capability of two-phase flow maps for microchannel condensation of R-134a at low mass flux conditions

Creator:: VanderPutten, Michael A.
Abstract:: Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...

Reliability Analysis of a Freeze Desalination System

Creator:: Boschetti Tofano, Francisco A.
Abstract:: The unsustainable use of fresh water sources and unavailability of fresh water in certain parts of the world have created a demand for water desalination systems. Desalination methods are effective at producing consumable water, but often require large scale setups, high energy consumption, and careful maintenance. A team of students...
