Tribo-dynamics modeling and analysis of key friction pairs in scroll compressor with floating fixed scroll design

Engineering Applications of Computational Fluid Mechanics, 2022
The fixed scroll of the scroll compressor is usually immovable, and the deformation of the scrolls may lead to the operation stuck, which may be avoided by designing the fixed scroll as floating one.

Some design problems of scroll compressor.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1986
The design problems of scroll compressors are discussed in this paper. The critical machine element in a scroll compressor is the thrust bearing when the compressor is employed for air conditioning and refrigeration, over a long period of operation. Not only the thrust, but also the moment acts on the thrust bearing.

Derivation of Optimal Scroll Compressor Wrap for Minimization of Leakage Losses [PDF]

, 2012
The scroll wraps of a scroll compressor play a very important role in the compressor’s efficiency due to their impact on leakage and leakage irreversibilities. In this work, a short summary of the scroll compressor geometry is presented.

Numerical Simulation of Wrap Scroll Temperature for Refrigeration and Air Conditioning Compressors [PDF]

, 2012
Being part of a model which simulates the whole consecutive overall compression process in a scroll compressor by solving equations of mass, momentum and energy balance for fluid refrigerant (Rovira et al.,2006), an updated version is presented.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...
