Sauna Online notes

2 months ago

Here are some of the nerdy things I have added to my notes over the years to achieve maximum realism. Also don’t count on my accuracy here, I’m half just pretending I know what I’m doing:

Room Specs

  • Dimensions (L x W x H in meters): Because size matters, right? Well, kinda. It affects how the heat spreads and how much space players have.

  • Volume (m³): Calculated from the above. Helps figure out air mass and all that good stuff.

Starting Conditions

  • Initial Air Temp (°C): Kicking things off at a chill 20°C before we turn up the heat.

  • Initial Humidity (%): Starting dry at around 30% to mimic that classic sauna vibe.

  • Air Pressure (kPa): Keeping it standard at 101.325 kPa because physics, man.

Ventilation

  • Air Changes per Hour (ACH): Think of it as how much we let fresh air in to keep the sauna from turning into a sweaty nightmare.

Heater Setup

  • Fixed Heater Power (W): Players can’t choose their heater’s wattage—it’s set to keep things balanced. No heater hogging here!

  • Heater Efficiency (%): Not all power turns into heat. Usually around 80-90% efficient because, let’s face it, some energy gets lost somewhere.

Player Inputs

  • Water Amount (ml): You can’t tweak this, but it’s not always the exact same scoop every time. A bit randomized to keep things interesting, because who scoops the exact same amount every round?

Physics Stuff

  • Specific Heat Capacity of Air (1005 J/kg·K): Fancy term for how much energy the air can hold before it heats up.

  • Specific Heat Capacity of Water (4186 J/kg·K): Not really much to add here.

  • Latent Heat of Vaporization (2,260,000 J/kg): The magic number that turns your water splashes into glorious steam.

  • Thermal Conductivity of Air (0.025 W/m·K): How well heat moves through the air. Spoiler: not great, which is why saunas can get so toasty.

  • Universal Gas Constant (8.314 J/mol·K): Just another constant to make sure everything’s legit.

  • Gravity (9.81 m/s²): Keeps everything grounded, literally.

Derived Goodness

  • Mass of Air (kg): Based on room volume and air density. More air = more heat capacity.

  • Mass of Water Added (kg): Simple conversion from ml to kg. Easy peasy.

  • Evaporation Energy (J): How much energy it takes to turn your water into steam. Important for those dramatic steam bursts.

  • Heat Added by Heater (J): Total heat from your heater over time, factoring in efficiency. More heat = hotter vibes.

  • Final Air Temp (°C): What the sauna temp ends up being after all the heating and water throwing.

  • Final Relative Humidity (%): How steamy things get. High humidity = more intense sauna experience.

Extra Spice for Realism

  • Airflow Dynamics: Because nobody likes a stuffy sauna. Modeling how air moves keeps things breathable.

  • Material Properties: Different woods handle heat differently. Cedar vs. pine? Big difference, trust me.

  • Steam Interaction: Realistic condensation and steam visuals to make you feel like you’re really there
