Book Description
This book mainly focuses on the understanding of basic concepts related Hydrodynamic Lubrication. In this more emphasis is given on steadily loaded oil film Journal Bearings. It includes discussion on derivation of generalised Reynold's equation for specific cases of Journal Bearing. In case of steadily loaded Journal Bearings viscosity is assumed to constant. But in reality because of rise in temperature, viscosity of oil film changes. In this book effect of variation of viscosity on the performance of Journal bearing is discussed. Plots of steady state, dynamic and thermo-hydrodynamic analysis are included in this book.

Book Description
Hydrodynamic Lubrication is the culmination of over 20 years close, collaborative work by the five authors and discusses the practical use of the formalization of low pressure lubrication. The work concentrates on the developments to journal and thrust bearings and includes subjects such as: • the dynamic behaviour of plain and tilting-pads • the thermal aspects • the positive and negative effects of non-cyclindricity and shape defects resulting from manufacturing or operation • the effects of inertia • the appearance of Taylor's vortices and of turbulence and their repercussions. The book contains an abundance of test results objectively compared with theoretical conclusions and a chapter on "technical considerations" to ensure that draft mechanisms will work satisfactorily under the imposed conditions. Hydrodynamic Lubrication is an essential reference book for future and practising engineers who want to put hydrodynamic and hydrostatic journal bearings and thrust bearings into operation under conditions of total safety.

Book Description
TRIBOLOGY – the study of friction, wear and lubrication – impacts almost every aspect of our daily lives. The Springer Encyclopedia of Tribology is an authoritative and comprehensive reference covering all major aspects of the science and engineering of tribology that are relevant to researchers across all engineering industries and related scientific disciplines. This is the first major reference that brings together the science, engineering and technological aspects of tribology of this breadth and scope in a single work. Developed and written by leading experts in the field, the Springer Encyclopedia of Tribology covers the fundamentals as well as advanced applications across material types, different length and time scales, and encompassing various engineering applications and technologies. Exciting new areas such as nanotribology, tribochemistry and biotribology have also been included. As a six-volume set, the Springer Encyclopedia of Tribology comprises 1630 entries written by authoritative experts in each subject area, under the guidance of an international panel of key researchers from academia, national laboratories and industry. With alphabetically-arranged entries, concept diagrams and cross-linking features, this comprehensive work provides easy access to essential information for both researchers and practicing engineers in the fields of engineering (aerospace, automotive, biomedical, chemical, electrical, and mechanical) as well as materials science, physics, and chemistry.

Book Description
This book is concerned with theoretical study for the thermal effects of the hydrodynamic journal bearings lubricated by ferrofluids with couple stresses. The study is generalize such that it covered both Newtonian and non-Newtonian behavior of the lubricant. Based on the momentum and continuity equations for ferrofluid under an applied magnetic field, a pressure differential equation (modified Reynolds equation) has been obtained. Assuming linear behavior for the magnetic material of the ferrofluid, and using carrying current concentric finite wire magnetic field model, the magnetic force was calculated. A modified Reynolds equation is obtained and it is simultaneously solved with the energy equation numerically by the finite difference technique. The pressure and temperature distributions have been obtained. The solution renders the bearing performance characteristics namely; load carrying capacity, attitude angle of the journal center, frictional force at the journal surface, friction coefficient and bearing side leakage.

Book Description
Thermohydrodynamic Instability in Fluid-Film Bearings aims to establish instability criteria for a rotor-bearing system associated with fluid-film journal bearings. • It focuses on how the influencing factors such as rotor flexibility, manufacturing imperfections such as residual shaft unbalance, and service-related imperfections such as uneven wear affect the stability of a rotor-bearing system • It shows how the specific operating conditions such as oil inlet temperature, inlet pressure, and inlet position of a rotor-bearing system directly influence the system stability • General design guidelines have been summarized to guide the engineering system design and the correction of failure and/or malfunction

Book Description
Introduction The plain hydrodynamic journal bearing configurations are widely being used in engineering applications due to their ability to provide superior performance and relative ease in manufacturing. These bearings are subjected to more stringent and severe operating conditions. When the fluid-film bearings operate under high speed and high load, heat is generated within the oil film due to the shearing of the lubricant, and the temperature rise of the lubricating fluid film and the bearing surface takes place. This causes a significant reduction of the viscosity of the lubricant which in turn reduces the minimum fluid-film thickness. Thus, the flow field of the lubricant is modified, which affects the bearing performance. Also, the plain journal-bearing system undergoes elastic deformation when operating under heavy loads.
