Purpose – To prepare surfactants and use as pour point depressants for a waxy gas oil. Design/methodology/approach – Some anionic surfactants (Calcium O, P.dioctyl benzene sulphonate and calcium hexadecyl benzene sulphonate) were prepared in the laboratory. The physicochemical characteristics...
Purpose – To analyse a self‐acting parallel surface thrust bearing using a proposed feedforward neural network. Design/methodology/approach – Firstly, a one‐piece hydrodynamic thrust bearing with an initially flat surface is analysed, designed and tested. Analysis of the configuration used is...
Purpose – The purpose of this paper is to know the effect of graphite particles distribution on wear behavior of ingots of an aluminium‐graphite, Al‐Gr (p) , composite. Design/methodology/approach – By SEM and optical microscope, it was observed that the graphite particles were entrapped and...
Purpose – To prepare semi‐synthetic oils satisfying the classification API SF/CC and SAE 10W30 from mineral base oils derived from high paraffinic petroleum, synthetic alkylbenzenes base oils, and suitable additives. Design/methodology/approach – The mixtures of base mineral oils of deep...
Purpose – The main purpose of the study is to develop a theoretical model being capable of analysing the sealing and hydrodynamic‐hydrostatic lubrication mechanisms occuring between the mating surfaces of mechanical face seals. Design/methodology/approach – The theoretical model developed is...
Purpose – Hybrid bearings have found increasing applications in various machines owing to their large number of favorable characteristics like high load carrying capacity, increased minimum fluid film thickness, long life and increased damping making them attractive for various applications such...
