I stand corrected; for the stuff that you are doing, I believe the code
block name needs to go to #+NAME instead of to :noweb-ref.

Below works (Hit C-c C-c in the second source block and approve evaluating
that code block:

* noweb reference with argument

#+NAME: sh-print-something
#+BEGIN_SRC shell :var str=""
echo echo $str
#+END_SRC

#+BEGIN_SRC shell :results output :noweb yes
echo "hello, "
<<sh-print-something(str="stardiviner")>>
#+END_SRC

#+RESULTS:
: hello,
: stardiviner

Changes:

(1) Switched back to #+NAME from :noweb-ref. Looks like if you need to pass
args, the reference name needs to be a code block name because
<<foo(bar=1)>> inserts the *results* of the code block "foo", not "foo" as
it is.
(2) So in the first block, you need to have code that *outputs* "echo $str"
with $str set to your set arg.
(3) Use shell instead of sh.

To stress the point of "<<foo(bar=1)>> inserts the *results*", even the
below would work the same way as we care about the results output by the
first block, not how those results are obtained.

* noweb reference with argument

#+NAME: sh-print-something
#+BEGIN_SRC python :var str="foo" :results output
print('echo "' + str + '"')
#+END_SRC

#+RESULTS: sh-print-something
: echo "foo"

#+BEGIN_SRC shell :results output :noweb yes
echo "hello, "
<<sh-print-something(str="stardiviner")>>
#+END_SRC

#+RESULTS:
: hello,
: stardiviner
