Study of Turbulent Models in Jet Impingement at Different Cross-Flow Conditions

Thermal Performance of Jet Impingement with Spent Flow Management

The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...

Numerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel

Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

Single Jet Mixing at Arbitrary Angle in Turbulent Tube Flow

An asymptotic procedure is presented to evaluate the tracer trajectory in a two-stream turbulent pipe mixing unit with an oblique branch. The proposed mixing jet trajectory estimate is compared with the existing experimental data and used to calculate the critical mixing conngurations. In addition, it is shown that the well-known tracer jet proole can be recovered for the case of a normally iss...
