RISLinear Stability Analysis of Short Porous Journal Bearings—Use of the Brinkman Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: On the basis of a Brinkman model (BM), this paper predicts that the effects of viscous shear stresses on the linear stability of short porous journal bearings are apparent and not negligible. ...
On the Lubrication of Short Porous Journal Bearings—Use of the Brinkman Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the Brinkman model (MB), this paper concerns the more realistic influence of viscous shear stresses on the lubrication performance of short porous journal bearings. Compared with those ...
A Fully Wet and Fully Dry Tiny Circular Fin Method for Heat and Mass Transfer Characteristics for Plain Fin-and-Tube Heat Exchangers Under Dehumidifying Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study proposes a new method, namely the “fully wet and fully dry tiny circular fin method,” for analyzing the heat and mass transfer characteristics of plain fin-and-tube heat exchangers ...
Mixed Finite-Element Analysis of Thick Doubly Curved Laminated Shells
Publisher: American Society of Civil Engineers
Abstract: A mixed finite-element scheme based on a discrete layer, high-order deformation theory is proposed, in this paper, for the analysis of thick, doubly curved laminated shells. The three-dimensional (3D) elasticity solutions ...
Stress and Displacement of Thick Doubly Curved Laminated Shells
Publisher: American Society of Civil Engineers
Abstract: A discrete‐layer, high‐order theory for the stress and displacement analyses of thick, doubly curved laminated shells is presented. The displacements of the shell in the theory are assumed to be layer‐by‐layer high‐order ...
Airflow Management on the Efficiency Index of a Container Data Center Having Overhead Air Supply
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effect of airflow managements on the efficiency index of a small container data center having overhead air supply is reported in this study. Seventeen arrangements and configurations regarding the airflow and blockage ...
Roughness Effects on the Dynamic Coefficients of Ultra-Thin Gas Film in Magnetic Recording
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stiffness and damping coefficients of a slider gas bearing operating under arbitrary Knudsen number are calculated. A perfect gas is used as the lubricant, and its behavior is described ...
Frictional Performance of U-Type Wavy Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements of the pressure drops for water flowing in small diameter tubes having U-type wavy configuration are presented. The inner diameters of the test copper tubes (D) are 3.43, 5.07, ...
Computational Fluid Dynamics Study on Heat Transfer Augmentation in Tube With Various V-Cut Twisted Tape
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comparative study on the enhancement mechanism by various twisted tapes (TTs) in association with the local flow pattern is investigated in detail via computational fluid dynamics (CFD). The effect of gap between TT and ...
Nonlinear Rupture Theory of a Thin Liquid Film With Insoluble Surfactant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effects of insoluble surfactant on the dynamic rupture of a thin liquid film coated on a flat plate are studied. The strong nonlinear evolution equations derived by the integral method are ...
