Flow and heat transfer inside a nonisothermal, incompressible, thin-Ž lm squeezing bearing are analyzed. The governing equationshave been nondimensionalizedand reduced to simpler forms based on an order of magnitude analysis. Various analytical solutions for the temperature distribution and Nusselt number under dierent physical constraints are obtained. The in uence of the thermal squeezing pa...

abstract background: accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences. one of the most common methods of airway clearance is endotracheal suctioning. in order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy techniques can be used at the time of expirat...

It is claimed that suddenly squeezing a newborn baby's trunk with a pressure of 3-4 kPa produces a flow volume curve that can be used to measure the function of the small airways. If the squeeze is applied during expiration rather than at the end of inspiration, however, anomalous results may be obtained. One possible explanation is that the babies are limiting expiratory flow by making inspira...

We develop and validate an efficient lattice kinetic Monte Carlo (LKMC) method for simulating particle aggregation in laminar flows with spatially varying shear rate, such as parabolic flow or flows with standing vortices. A contact time model was developed to describe the particle-particle collision efficiency as a function of the local shear rate, G, and approach angle, θ. This model effectiv...

Microfluidic flow-focusing devices offer excellent control over fluid flow, enabling formation of drops with a narrow size distribution. However, the throughput of microfluidic flow-focusing devices is limited and scale-up through operation of multiple drop makers in parallel often compromises the robustness of their operation. We demonstrate that parallelization is facilitated if the outer pha...
