Numerical modeling of the hydrodynamics of gas fluidized beds

Creator:: Wang, Yusan
Abstract:: This research involves a numerical study of the hydrodynamics of gas fluidized beds. We use the continuum model, treating both gas and particles as interpenetrating continua. The motion of gas and particles is strongly coupled by the interactions between them. For simplicity, we only consider drag forces. We use MacCormack's...

A simplified model of heat transfer between large-particle gas-fluidized beds and immersed surfaces

Creator:: Bakke, Paul D.
Abstract:: A simplified model of the combined particle convective and radiative components of heat transfer between large-particle gas-fluidized beds and immersed surfaces was developed. This analytical model was based on the single particle formulation of Adams and Welty [4,9], with the added assumptions of one-dimensional heat conduction in the particle and...

A theoretical study of the radiative contribution to heat transfer between a high-temperature, large-particle gas-fluidized bed and an immersed tube

Creator:: Mahbod, Bahram
Abstract:: An analytical model of the radiative contribution to the total heat transfer between a large-particle (greater than 1 mm) gas-fluidized bed and an immersed horizontal tube is discussed. The model is applied to the case of a bubbling bed and the emulsion phase contribution is obtained from a detailed analysis...

An analytical model of radiative and convective heat transfer in small and large particle gas fluidized beds

Creator:: Fatani, Abdulhadi Ahmed
Abstract:: A complete analytical model of radiative and convective heat transfer to a horizontal tube in small and large particle gas fluidized beds has been developed. In the model the bed of particles consists of an emulsion phase and a bubble phase. The emulsion phase is approximated by a series of...

An experimental investigation of radiative and total heat transfer around a horizontal tube immersed in a high temperature gas-solid fluidized bed

Creator:: Alavizadeh, Seyed Nasser
Abstract:: This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures.Total heat transfer was also measured in order to assess the relative radiation contribution.The radiation measurement probe employs a silicon...

Empirical Analysis of Two-Phase Confined Impinging Jet Heat Transfer

Creator:: Damiano, Adam P.
Abstract:: Advances in electronics fabrication, coupled with the demand for increased computing power, have driven the demand for innovative cooling solutions to dissipate waste heat generated by these devices. To meet future demands, research and development has focused on robust two-phase heat transfer devices. A confined impinging jet is explored as...

An analytical model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed

Creator:: Adams, Ronald Lynn
Abstract:: A steady gas convection model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed is presented. Contributions due to flow within attached bubbles as well as the interstitial voids are included. The interstitial flow is approximated as flow within a series of double cusped channels and...

Designing and creating the Oregon State age and disability simulation suit

Creator:: Rahrer, Adam P.
Abstract:: Over 54 million people report having disabilities in the United States. In addition, there are 40.3 million people 65 years and older living in America. As the population continues to live longer and problems with obesity continue to increase, the number of people with limited capabilities will escalate as well....
