Thermal flow in an aircraft wing leading-edge anti-icing system is a complicated physical phenomenon and remains a challenging research topic of modeling and analysis. This paper presents a complete three-dimensional simulation of a wing segment including the piccolo-type thermal anti-icing bays inside the leading edge is presented. The Navier–Stokes analysis has been conducted for the integrat...

Abstract An unsteady local heat transfer in an air synthetic non-steady-state jet impingement onto a flat plate with variation of the Reynolds number, nozzle-to-plate distance and pulses frequency is experimentally numerically studied. Measurements averaged pulsating at stagnation point are conducted using flux sensor. The axisymmetric URANS method stress model used for numerical simulations. F...

Title of Document: FORCE FED MICROCHANNEL HIGH HEAT FLUX COOLING UTILIZING MICROGROOVED SURFACES Edvin Cetegen, Doctor of Philosophy, 2010 Directed By: Michael Ohadi, Professor Department of Mechanical Engineering Among other applications, the increase in power density of advanced electronic components has created a need for high heat flux cooling. Future processors have been anticipated to exc...

Heat transfer by flame jet impingement is widely used in many of the industrial and domestic applications like heating metal bars, scrap melting, shaping glass, slab cutting, cooking others. Aim present experimental work to study an effect swirl on a local heat flux distribution inverse diffusion (IDF) impinging flat target surface coaxial tube burner. The twisted tape twist ratio 3 (correspond...

Abstract This work reports the results of paired experiments for a complex internal cooling flow within gas turbine vane using magnetic resonance velocimetry (MRV) and steady-state infrared (IR) thermometry. A scaled model leading edge insert with multi-pass impingement was designed, built stereolithography fabrication methods, tested MRV techniques to collect three-dimensional, three-component...

the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

This paper presents an experimental investigation on the primary and secondary peak heat transfer characteristics of obliquely (45°) impinging jet a flat smooth target surface. Local convective coefficients have been calculated through transient liquid crystal thermography technique employing one-dimensional semi-infinite conduction model for The effects Reynolds number (Re) jet-to-target spaci...
