RISDevelopment of Long-Term Performance Correlation for Solar Thermosyphon Water Heater
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A semi-empirical long-term performance correlation for a solar thermosyphon water heater was derived. The derivation used the simulated results from a well-tested computer program developed previously. ...
A Method for Optimal Tolerance Selection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces and formalizes a method for specifying independent functional tolerances in an optimal least-cost manner. Previous methods have been thwarted by formulation and computational ...
An Automation of Collector Testing and Modification of ANSI/ASHRAE 93-1986 Standard
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The steady-state performance test of solar collectors using ANSI/ASHRAE 93-1986 Standard was revised and an automation for the testing was carried out in the present study in order that the ...
A Performance Test Method of Solar Thermosyphon Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of test for the thermal performance rating of thermosyphon systems is developed in the present study. It is suggested that the overall performance rating of a solar thermosyphon system ...
Identification of Solar Collector Dynamics Using Physical Model-Based Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A system dynamics model of flat-plate solar collectors was derived and identified here. A nonlinear physical model was first derived from a two-node concept and energy conservation principle. ...
A System Dynamics Model of Fire-Tube Shell Boiler
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A system dynamics model of fire-tube shell boiler was developed. The derivation of the dynamics model started with a nonlinear time-variant dynamic modeling based on the transport phenomena in ...
System Dynamics and Control of a Linear Compressor for Stroke and Frequency Adjustment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents results of an investigation on the system dynamics and the controller design of a linear compressor for stroke and frequency adjustment. A system dynamics model was derived ...
Effects of Surface Mass Transfer on Free Convection Flow Over Vertical Cylinder Embedded in a Saturated Porous Medium
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heat-transfer characteristics for free convection associated with isothermal vertical cylinder with surface mass transfer (blowing or suction) embedded in a saturated porous medium are analyzed. ...
Active Control of Translating Media With Arbitrarily Varying Length
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The general control laws for pointwise controllers to dissipate vibratory energies of translating beams and strings with arbitrarily varying length are presented. Special domain and boundary control ...
Hydrodynamic Instability of Solar Thermosyphon Water Heaters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow instability of a solar thermosyphon water heater is studied analytically. A system dynamics model is derived by means of a one-dimensional approach and a linear perturbation method. ...
