Abstract
In one example, a liquid mixture nozzle for flowing a liquid mixture therethrough includes a body having a flow inlet and a flow outlet. The flow inlet is configured to couple to a first piece of piping and the flow outlet is configured to couple to a second piece of piping. The liquid mixture nozzle also includes a converging section having a decreasing diameter positioned adjacent the flow inlet, an orifice positioned at a narrow end of the converging section, an intermediate section having a constant diameter positioned adjacent the orifice, a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.
Claims25
A liquid mixture nozzle for flowing a liquid mixture therethrough, comprising:
- a body having a flow inlet and a flow outlet, the flow inlet configured to couple to a first piece of piping, and the flow outlet configured to couple to a second piece of piping;
- a converging section having a decreasing diameter positioned adjacent the flow inlet;
- an orifice positioned at a narrow end of the converging section;
- an intermediate section having a constant diameter positioned adjacent the orifice;
- and
- a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.
A flow system, comprising:
- a flow inlet pipe;
- a flow outlet pipe;
- and
- a first liquid mixture nozzle connected to the flow inlet pipe at an upstream end of the liquid mixture nozzle, and connected to the flow outlet pipe at a downstream end of the liquid mixture nozzle, the liquid mixture nozzle comprising:
- a body having a flow inlet and a flow outlet;
- a converging section having a decreasing diameter positioned adjacent the flow inlet;
- an orifice positioned at a narrow end of the converging section;
- an intermediate section having a constant diameter positioned adjacent the converging section;
- and
- a diverging section having an increasing diameter positioned adjacent the intermediate section and the flow outlet.
A method for dispersing particles in a drilling mud, the method comprising:
- flowing the drilling mud through a converging flow section to increase the velocity of the drilling mud;
- flowing the drilling mud through an orifice located downstream of the converging section;
- and
- flowing the drilling mud through a diverging section located downstream of the orifice, thereby generating turbulence within the drilling mud to enhance dispersing of particles within the drilling mud.
