Analysis of a counterflow indirect evaporative cooling and liquid desiccant dehumidification system (Texas A&M University. Libraries, 1986)A solar-fired liquid desiccant cooling and dehumidification system has been proposed, analyzed and simulated on a digital computer. The entire study comprised of three distinct but related stages. The first phase of the ...
-
(Texas A&M University. Libraries, 1988)A new analysis procedure which solves for leakage, reactive force, and rotordynamic coefficients of eccentric annular liquid and gas pressure seals is presented in this dissertation. This analysis procedure is based on a ...
-
(Texas A&M University. Libraries, 1985)A parametric study of the forces governing the liquid vapor interface was performed for the purpose of determining the capillary priming characteristics of Grumman's dual passage, monogroove heat pipe when subjected to ...
-
(Texas A&M University. Libraries, 1972)In this study the pressure effect on the inversion temperature of gases was determined. The gases selected for this study were two of the more common ones, namely, air and nitrogen. An equation of state is a means for ...

Approximate solution for a rolling contact problem over a relatively general viscoelastic half-space (Texas A&M University. Libraries, 1977)An approximate method is developed to predict the coefficient of friction and normal load for the problem of a rigid circular cylinder moving across a relatively general viscoelastic half-space with constant velocity. The ...

(Texas A&M University. Libraries, 1971)This study, using the method described by Hartley and Rao [10], derives confidence regions for the ratios of variances in random model. Each region is compared with a confidence region derived by Wald [22]. We derived ...
-
(Texas A&M University. Libraries, 1973)Boiling in small cross section channels has not received as much attention as in large cross section channels. It is noted in the literature that higher heat transfer coefficients can be expected in the small cross section ...

(Texas A&M University. Libraries, 1995)For the capillary flow in a groove channel, the analysis of axial variation of the intrinsic meniscus as well as that of evaporating thin film region was carried out. Various approximate analytical solutions were developed ...
-
(Texas A&M University. Libraries, 1994)An experimental and analytical investigation of forced convective condensation in smooth circular tubes is performed for R-22 and R32+R125 mixture (50% by mass). The refrigerant is condensed by water inside a 0.315 inch ...
-
(Texas A&M University. Libraries, 1969)A general nonlinear theory of shells is derived. The theory is valid for large extensions, shear and rotations. The large rotations of the shell are described in detail. The measures of bending deformation then are written ...
-
(Texas A&M University. Libraries, 1987)The control volume finite element method is applied to transient laminar free convection between vertical parallel heated plates. The results are compared with those obtained from the alternating direction implicit method ...
-
(Texas A&M University. Libraries, 1990)A very important application of feedback is servo-tracking, or the ability of a closed-loop system to track a given class of reference input signals, while rejecting a given class of external disturbances, in the sense ...
-
(Texas A&M University. Libraries, 1974)A stress testing machine was designed and built to study the combined effect of mean static stress and reversed shear stress on the fatigue life of a material. Aluminum alloy 7075-T6 was tested under different combinations ...
-
(Texas A&M University. Libraries, 1977)Cylindrical specimens of 7075-T6 aluminum alloy were subjected to reversed shear stress and static mean stress to study the effect of mean static tensile stress on cumulative fatigue damage under reversed shear stress. The ...
-
(Texas A&M University. Libraries, 1989)The objective of this study is to identify the deformation micromechanisms operative in carbon fibre reinforced polymer composites and in the base polymers that act as the matrix material. The aim is to understand the ...
-
(Texas A&M University. Libraries, 1991)This study discusses the derivation and assessment of a new two-scale dissipation equation, the genesis of which begins with a different fundamental equation than previous multi-scale or single-scale models. The new approach ...
-
(Texas A&M University. Libraries, 1992)In this research, a design methodology is developed for realizing low order robust controllers for flexible structures modelled as partial differential equations (PDEs). The efficacy of the methodology is illustrated by ...

Determination of the mode I delamination fracture toughness of multidirectional composite laminates (Texas A&M University. Libraries, 1988)The objective of this study is to develop and verify a theoretically-based method for characterizing mode I delamination fracture of composite laminates. Attention focuses on the special problems associated with delamination ...
