Although the effects of jet fires are often limited to rather short distances, if their flames impinge on a pipe or vessel collapse can occur in very times. In such cases, heat flux affected equipment is high and wall temperature increase rapidly. This happen parallel pipelines, release occurs impinges another one. Nevertheless, fire impingement has been scarcely studied. this communication res...

With decrease in size of electronic equipment’s, effective heat removal is a major challenge these days. Present work focuses on implementation novel hybrid method which helps attain transfer enhancement. An experimental investigation carried out to study effect pulse air jet local distribution flat surface. Effect nozzle plate distance (z/d = 2 6), Reynolds number (5000 9000), pulsating freque...

Accidental release scenarios such as flammable gas leaks or ruptures of pipes and pressurised process-equipment normally originate high velocity jets which, if ignited, give rise to jet fires. Although the direct effects of jet fires are considered to be relatively smaller than that associated to other types of fires, they are characterized by high heat fluxes and, especially if there is flame ...

Double-wall cooling structures are commonly used to enhance the heat transfer in combustor liner and aerofoil internal within gas turbine engines other industrial applications. This is first study adopt a novel reverse jet impingement technique into double-wall structure order achieve higher rate with relatively lower pressure drop. paper uses computational fluid dynamics crossflow, nozzle conf...
