Structure and Actuation of Cephalopod-Inspired Soft Robots

Creator:: Olson, Gina M.
Abstract:: Cephalopod-inspired soft robot arms have been studied as a new type of manipulator. These arms have been proposed for reach and grab tasks, underwater locomotion via swimming and walking, and robotic surgery. However, the capabilities of existing soft arms are limited to simple motions and light loads. Arm design has...

Orb Web Vibrations: Modeling, Localization, and Measurement

Creator:: Otto, Andrew W.
Abstract:: The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

Experimental studies of a partially defluidized bed with immersed heat exchange tubes

Creator:: Sitthiphong, Norkun
Abstract:: The object of this research study is to investigate and provide some fundamental information about bed slumping in a partially defluidized bed combustor. Due to the difficulty in making measurements and observations at high temperature, a dynamically similar cold phase fluidized bed was used to model the high temperature case....

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...

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...

Experimental studies of heat transfer with an array of horizontal tubes immersed in a high-temerature fluidized bed

Creator:: Goshayeshi, Ali
Abstract:: An experimental study is described in which time-average local heat transfer coefficients were obtained for arrays of horizontal tubes immersed in a hot fluidized bed. Spatial-averaged heat transfer coefficients, computed from local values, are also reported. Refractory particles with surface mean diameters of 2.14 mm and 3.23 mm were fluidized...
