“…The nonlinear Reynolds equation was derived and solved to study the pressure distribution and load capacity of aerostatic bearings [5][6][7]. It was noted that the throttle orifices all acted as point sources, which could not provide detailed characteristics of the fluid flow, especially the flow field near the outlet of the orifice restrictor in aerostatic bearings.…”

“…where is the radius of the journal bearing, h is the gas film thickness, is the dynamic viscosity of air, and is the angular velocity of rotor. The static Reynolds equation and the perturbation equations are obtained by the perturbation method [13][14][15][16][17][18][19] and solved by the finite difference method [20][21][22]. Taking the thrust bearing as an example, the nondimensional static Reynolds equation can be written as:…”

“…Ayrıca sürekli bir hava beslemesi olduğu için beklendiği gibi en yüksek basınç orifislerin karşısında oluşmakta ve yatağın uçlarının atmosfere açık olmasından dolayı; yatağa 2 atm basınçta giren hava, her iki uçtan atmosfer basıncına düşerek çıkmaktadır. Şekil 4'de verilen basınç dağılımı niteliksel olarak literatürdeki [16], [19] ve [26]. çalışmaları ile uyumluluk göstermektedir Yatak ile rotor eş merkezli değilse, yatak ve rotor arasındaki boşluğa bağlı olarak basınç dağılımı da değişecektir.…”
