Abstract
Embodiments of apparatus are disclosed for affecting working fluid flow in a system that delivers material between two locations by carrying the material in the working fluid. For example, embodiments of the disclosed apparatus may be used in an internal combustion engines to carry fuel droplets to a combustion area using air as the working fluid. The apparatus may include a passage including a funnel portion and tumble area that direct working fluid into a stratified stream. The stratified stream may include an outer boundary flow having a toroidal and/or helical flow characteristic and an inner flow carrying injected material that is bound by the outer flow.
Claims20
A stratified stream system comprised of:
- a passage extending from an input port to an exit port, said passage configured to receive a supply of working fluid at the input port;
- a first portion of said passage configured to induce a Venturi effect and a Coanda effect in the working fluid;
- and
- a second portion of said passage between the first portion and the exit port, said second portion configured to complete formation of a stratified stream flow of said working fluid.
A stratified stream system comprised of:
- a passage extending from an input port to an exit port;
- a funnel portion in said passage, said funnel portion having a smooth surface;
- and
- a tumble area having a non-smooth surface, said tumble area provided in said passage between the funnel portion and the exit port.
A stratified stream system comprised of:
- a passage;
- a first means for inducing a Venturi effect and/or a Coanda effect in a working fluid in the passage;
- and
- a second means for inducing a torodial flow in an outer portion of the working fluid, wherein the first means is adjacent to the second means in the passage.
