The Science of Ship Design
gt;gt; DESIGNING SOMETHING LIKE THE HULL OF A SHIP CAN BE AN EXPENSIVE PROCESS. SO HOW DO YOU RIGOROUSLY TEST OUT A DESIGN BEFORE YOU EVEN BUILD IT? A UNIQUE RESEARCH PROGRAM AT THE UNIVERSITY OF IOWA MAKES THAT.
POSSIBLE, USING SOPHISTICATED SOFTWARE, MODEL SHIPS, AND AN ENORMOUS INDOOR POOL. PROFESSOR FRED STERN LEADS THE UNIVERSITY OF IOWA’S SHIPHYDRODYNAMICS PROGRAM, THE HOME OF THIS HIGHTECH FACILITY. gt;gt; THESE ARE CALLED WAVE BASINS.
YOU CAN SEE THE WAVEMAKERS AT THE FAR END HERE. THEY’RE PLUNGER TYPE. THEY GO UP AND DOWN. THEY GENERATE EITHER REGULAR OR IRREGULAR WAVES IN THE BASIN. THE NEXT PART FOR US, THEN, IS THE CARRIAGE.
THIS IS A CUSTOMDESIGNED CARRIAGE. IT FOLLOWS THE MODEL. THERE’S TARGETS ON THE MODEL THAT THE CAMERAS AND THE TRACKING SYSTEM USE. OURS IS UNIQUE INSOFAR AS IT’S DESIGNED SPECIFICALLY TO CARRY.
MEASUREMENT SYSTEMS TO MEASURE THE LOCAL FLOWS AROUND THE FREERUNNING MODELS. gt;gt; BELIEVE IT OR NOT, THIS NEARLY $5 MILLION FACILITY WAS DESIGNED AND BUILT PRIMARILY FOR THE PURPOSE OF VALIDATING OR TESTING COMPUTER CODE.
THAT CODE, CFDSHIPIOWA, IS A SIMULATION SOFTWARE DEVELOPED AT THE UNIVERSITY OF IOWA FOR THE OFFICE OF NAVAL RESEARCH. IN THE PAST, STERN AND HIS RESEARCH TEAM VALIDATED THE CODE BY RUNNING THEIR MODELS IN A 300FOOTLONG TOWING TANK, BUT.
AS COMPUTER POWER GREW AND THE CODE BECAME ABLE TO DO MORE ADVANCED SIMULATIONS, SO IT REQUIRED A MORE SOPHISTICATED TOOL FOR VALIDATING. gt;gt; OUR CODES DEVELOPED VERY RAPIDLY OVER THE LAST, REALLY, 5 TO 10 YEARS, TO THE POINT THAT.
Draw Necklines in Fashion Design Boat Necklines in Fashion Design
Alright. Now, we’re going to do my personal least favorite neckline. I don’t know why. It makes me think of like my Mom’s nineteen fifties Barbie dolls. But, not in a good way. It just seems really boring and I think it makes people look kind of wide. But, it’s your voice. Don’t let me influence you. It’s a boat neck style and in order to do it, you’re going to go from mid shoulder to mid shoulder. There’s your line and you want it straight across square, boring. And, then this one the three dimensional aspect of it you’re not going to see as much. It’s not going to be as noticeable, because it’s not up close to the neck. When it’s close to the neck like the last two that I showed you, you can wrap.
It around and show three dimensional style better. This, you just want to pretty much you can flub around with it. And, just make a little mark and then bring it down. And, there is your boat neck.
