I'd thought of naming chapters, but it just never panned out. To me, it restricted the chapters and can make the reader focus on that aspect alone and maybe miss something else. I'd rather keep it neutral with a number and let them draw their own conclusions.
I've also played with just scene breaks, no numbers. I've seen it done and it actually worked pretty well, however, I like chapters better, and I can't explain why.
I've also toyed with putting a date, or time, or location on each numbered chapter, like James Rollins and a few others. In a way, that keeps you attuned to the sequence. However, when I think of how I read, I usually gnore dates, times, numbers, and titles. Most of the time all of that detail does nothing for me. If it's only done at key points, I'm more likely to pay attention.
In the end, I number my chapters. If there is a prologue, I'll have a date and maybe time or location. Chapter 1 starts with "Present day."
In my latest icky bug, I have chapters but each chunk of chapters starts with a day. This story takes place over a week.
In my latest sci-fi thriller, I name major sections and have chapter numbers within each section.
You see? I can't even make up my mind! I guess, whatever fits.
