Predicting Droplet Sizes

Squeeze a bottle of cleaning spray, and the nozzle transforms a liquid jet into a spray of droplets. These droplets come in many sizes, and predicting them is difficult because the droplets’ size distribution depends on the details of how their parent liquid broke up. Shown above is a simplified experimental version of this, beginning with a jet of air striking a spherical water droplet on the far left. In less than 3 milliseconds, the droplet has flattened into a pancake shape. In another 4 milliseconds, the pancake has ballooned into a shape called a bag, made up of a thin, curved water sheet surrounded by a thicker rim. A mere 10 milliseconds after the jet and drop first meet, the liquid is now a spray of smaller droplets.

Researchers have found that the sizes of these final droplets depend on the balance between the airflow and the drop’s surface tension; these two factors determine how the drop breaks up, whether that’s rim first, bag first, or due to a collision between the bag and rim.

From drop to droplets. A water drop struck by an air jet deforms into a pancake shape before ballooning out into a thick-rimmed bag. Just 9.5 milliseconds after the jet, the bag and rim have broken into a spray of many droplet sizes.

In a local gardening group someone is asking how to kill Johnson grass, which is considered a weed in these parts. The irony of this response went unremarked, but I am still laughing about it:

"Use Roundup carefully and spot treat. I have used it for nearly 50 years with great success."

Such great success that after fifty years, you're still doing it! 🤣

Calling #glass wearers that use #cleaning #sprays

What brand do you use?

I really like the one from #Spex4Less as it has a good aroma.

The only other experience I have is one from #SpecSavers (okay, but not as good an aroma).

Both of these work as well as each other. And they work much better than just water, and more convenient than washing at a sink.
